Definitions
- Conventional articles of footwear often include two primary components: an upper and a sole structure.
- the upper provides a covering for the foot and securely positions the foot relative to the sole structure.
- the sole structure is secured to a lower surface of the upper and configured so as to be positioned between the foot and the ground when a wearer is standing, walking or running
- Sole structures are often designed so as to cushion, protect and support the foot. Sole structures may also be designed so as to increase traction and to help control potentially harmful foot motion such as overpronation.
- a primary element of many conventional midsoles is a resilient polymer foam material that extends throughout the length of the footwear.
- the physical characteristics a midsole largely depend on the density and other properties of the polymer foam material and on the dimensional configuration of the midsole. By varying these factors throughout the midsole, the relative stiffness, degree of ground reaction force attenuation, and energy absorption properties may be altered to meet the specific demands of the activity for which the footwear is intended to be used.
- a footwear sole structure may include a plurality of discrete sole elements defined by a plurality of sipes.
- the sipes may include a plurality of sipes that extend in a direction extending from a medial side of the sole structure to a lateral side of the sole structure (i.e., a mediolateral direction) and be rearwardly angled.
- the rearwardly-angled mediolateral sipes may be located in a midfoot region.
- the sole structure may include a plurality of additional sipes having longitudinal, transverse and/or other orientations.

- a hindfoot element of a sole structure is an element having one or more portions located under, to the lateral and/or medial side of, and/or behind a wearer's hindfoot (or portion thereof) when the shoe is worn.
- the forefoot region may overlap with the midfoot region, as may the midfoot and hindfoot regions.
- a longitudinal axis refers to a horizontal heel-toe axis along the center of the foot, while that foot is resting on a horizontal surface, that is roughly parallel to a line along the second metatarsal and second phalanges.
- a transverse axis refers to a horizontal axis across the foot that is generally perpendicular to a longitudinal axis.
- a longitudinal direction is parallel (or roughly parallel) to a longitudinal axis.

- FIGS. 2E and 2F are area cross-sectional views taken from the locations indicated in FIG. 2A .
- FIG. 2G is a bottom view of shoe 200 .
- Shoe 200 includes an upper 201 .
- Upper 201 creates an interior 215 ( FIGS. 2E and 2F ) configured to receive a foot of a shoe 200 wearer.
- upper 201 can be similar to uppers described in commonly-owned U.S. Pat. No. 6,990,755, titled “Article of Footwear with a Stretchable Upper and an Articulated Sole Structure,” which patent is incorporated by reference herein.
- Shoes according to various embodiments can include sole structures such as those described herein in combination with any of various types of uppers. Because the details of such uppers are not pertinent to understanding sole structures disclosed herein, upper 201 is shown generically in FIGS. 2A-2F using a broken line or stippling.
- upper 201 may include a lasting element (e.g., a Strobel) 203 .
- Lasting element 203 may be stitched to edges of upper 201 along a seam 204 , with seam 204 located near a periphery of a footbed.
- An insole 205 can be positioned adjacent to the top surface of lasting element 203 within interior 215 .
- Insole 205 may contact the bare or socked plantar surface of the wearer foot along the entire length of the foot.
- Insole 205 may be compressible and/or have an orthotic shape to conform to a wearer foot.
- sole structure 202 primarily comprises a single-piece midsole 206 .
- a top surface 207 of midsole 206 is bonded to the underside of lasting element 203 and to border portions 214 of upper 201 located outside of seam 204 .
- Midsole 206 protects the foot of a shoe 200 wearer from ground surface material that might puncture or otherwise injure the skin on the underside of the foot.
- Midsole 206 also provides cushioning by attenuating ground reaction forces and absorbing energy when a wearer of shoe 200 walks or runs.
- Suitable materials for midsole 206 can include any of various polymer foams utilized in conventional footwear midsoles, including but not limited to ethylvinylacetate (EVA), thermoplastic polyurethane (TPU) and polyurethane foams.
- EVA ethylvinylacetate
- TPU thermoplastic polyurethane
- Midsole 206 may also be formed from a relatively lightweight polyurethane foam having a specific gravity of approximately 0.22, as manufactured by Bayer AG under the BAYFLEX trademark.
- Midsole 206 has an articulated structure that imparts relatively high flexibility and articulation.
- the flexible structure of midsole 206 is configured to complement the natural motion of the foot during running or other activities, and may impart a feeling or sensation of barefoot running In contrast with barefoot running, however, midsole 206 attenuates ground reaction forces and absorbs energy to cushion the foot and decrease the overall stress upon the foot.
- midsole 206 includes a plurality of midfoot sipes that accommodate transtarsal foot motion.
- midsole 206 includes a spanning portion 209 and an articulated portion 210 .
- Spanning portion 209 includes the portion of midsole 206 above sipes 212 .
- Articulated portion 210 includes a plurality of discrete sole elements 211 defined by sipes 212 . Sole elements 211 are connected to and extend downward from spanning portion 209 . Only the ends of certain sipes 212 and a portion of sole elements 211 can be seen in FIGS. 2A through 2D .
- sipes 212 and sole elements 211 can be seen in FIG. 2G , a bottom view of shoe 200 showing the exposed bottom surface of sole structure 202 .
- midsole 206 includes eighteen sipes 212 a through 212 r.
- Sipes 212 a through 212 r define numerous discrete sole elements 211 by exposing sides of those elements. This permits those discrete elements to move away from one another and allows midsole 206 to flex along sipes 212 .
- a medial side of sole element 211 a is exposed by sipe 212 a.
- a lateral side of sole element 211 a is exposed by sipe 212 b.
- sole element 211 a Front and rear sides of sole element 211 a are exposed by sipes 212 h and 212 i, respectively.
- the exposed sides of sole element 211 a allow sole element 211 a to separate from the sides of adjacent sole elements when a wearer steps on an uneven surface and/or when the wearer dorsiflexes, pronates, supinates or otherwise moves his or her foot.
- Other sole elements can similarly separate from adjacent sole elements. To avoid cluttering FIG. 2G with unnecessary details, only a few of sole elements 211 are marked or discussed.
- a sipe generally refers to a separation between sides of adjacent discrete sole elements.
- a sipe may leave little or no space between the sides of adjacent sole elements when the siped sole structure is unloaded.
- side faces of adjacent sole elements separated by a narrow sipe may actually be in contact with one another when the sole structure is unloaded, and there may only be space between those faces when the sole structure flexes along the sipe.
- a wider sipe may create a larger gap between sides of adjacent sole elements, and there may be space between those sole element sides in the unloaded sole structure.
- a sipe may have a portion (e.g., the deepest part of the sipe) in which adjacent sole elements are in contact when the sole structure is unloaded and another portion (e.g., the portion of the sipe near the bottom surface of the sole structure) in which there is a groove or other space between adjacent sole element faces in the unloaded sole structure.
- Sipes can be formed by molding, e.g., by including blades in a midsole mold corresponding to desired sipe locations. Sipes can also be formed by cutting sipes in a midsole or other sole structure using a knife or other tool. Sipes can also be formed using combinations of molding and cutting operations, as well as by other processes. In some embodiments, thinner sipes may be “knifed” (i.e., cutting with a blade), while wider sipes may be molded into a midsole. In some such embodiments, the molded-in sipes may be located in areas of a shoe where higher stresses may be expected (e.g., at the heel, where a step lands, and at the toe, where step-off occurs).
- Molded-in sipes may in some cases be more durable than knifed sipes, as all sides of the sipe are exposed to curing conditions and have an outer crust of cured polymer. Conversely, knifed sipes are cut into the midsole after curing. Thus, knifed sipes side edges and their junction with the spanning portion may constitute uncured polymer material that is less durable than cured polymer.
- sipes 212 a, 212 b, 212 c and 212 d are longitudinally oriented and extend in generally longitudinal directions.
- Sipe 212 a is located in the medial forefoot region and extends from forefoot sipe 212 f to midfoot sipe 212 k.
- Sipe 212 b is curved and extends from a front edge of outsole 206 in the toe region to hindfoot sipe 212 r.
- Sipe 212 c is also curved and extends from the front edge of outsole 206 to a rear edge of outsole 206 in the hindfoot region.
- Sipe 212 d is curved and extends from forefoot sipe 212 e to hindfoot sipe 212 r.
- Sipes 212 e through 212 r are transversely oriented and extend in generally transverse directions.
- Sipe 212 e extends from a lateral edge of outsole 206 to sipe 212 b.
- Sipes 212 f through 212 k, sipe 212 m, sipe 212 q and sipe 212 r extend from the lateral edge of midsole 206 to the medial edge of outsole 206 .
- Sipe 2121 extends from the midsole 206 lateral edge to the intersection of sipes 212 a and 212 k.
- Sipe 212 n extends from the midsole 206 medial edge to sipe 212 b.
- Sipe 212 o extends from the midsole 206 lateral edge to sipe 212 c.
- Sipe 212 p extends from the midsole 206 medial edge to the intersection of sipes 212 d and 212 o. Although sipe 212 l joins sipe 212 k just short of reaching the midsole 206 medial edge, sipe 212 l and the portion 212 k ′ of sipe 212 k to the medial side of sipe 212 a effectively form a single sipe that extends from the midsole 206 lateral edge to the midsole 206 medial edge.
- sipe depth (as a percentage of sole structure thickness) is maximized and the thickness of a spanning portion minimized so as to reduce the force needed to flex the sole structure along the sipe and to separate adjacent sole elements.
- the thickness t of spanning portion 209 over sipe 212 q under the footbed is relatively small compared to the depth d of sipe 212 q.
- longitudinally-oriented sipes 212 b and 212 c have not been shown in the rear face of transversely-oriented sipe 212 q.
- sipes 212 a through 212 d have been omitted from the area cross-sectional view of FIG. 2E .
- Sipe depth d and under-footbed spanning portion thickness t may vary within a particular shoe and among various embodiments.

- a ratio d/t is at least 1 over the majority of the length of those sipes. This may include, without limitation, sipes 212 l through 212 o. The ratio d/t over a majority of a sipe length may be greater (e.g., 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, etc.) for some or all sipes in the hindfoot and/or midfoot regions (including but not limited to sipes 212 l through 212 o ).

- sole structure 202 includes a spanning portion 209 and an articulated portion 210 as parts of a single integrally-formed midsole. Spanning portion 209 interconnects the discrete sole elements defined by the sipes of the articulated portion. This need not be the case, however.
- a lasting element or some other flexible member coupled to the underside of a lasting element may serve as a sole structure spanning portion. Individual sole elements could be cut or otherwise formed and then bonded to the bottom of that lasting element or other flexible member. In such an embodiment, the thickness t of the spanning portion could be the thickness of the flexible member bonded to the bottom of the lasting element. If the sole elements are bonded directly to the lasting element, t could equal zero.

- transverse sipes 212 k and 212 p through 212 r are roughly perpendicular to longitudinal axis A 21 .
- Each of transverse sipes 212 e through 212 j is oriented in a medial-to-lateral (i.e., mediolateral) direction and is forwardly angled.
- the angles in the forward lateral quadrants of the intersections of sipes 212 e through 212 j with axis A 21 are less than 90 degrees.
- each of sipes 212 l through 212 o is oriented in a mediolateral direction and is rearwardly angled. Angles in the forward medial quadrants of the intersections of sipes 212 l through 212 o with axis A 21 (e.g., angle b 22 ) are thus less than 90 degrees, as are angles in the rear lateral quadrants of such intersections. As indicated above, sipe 212 l and sipe portion 212 k ′ effectively form a single sipe that extends from the midsole 206 lateral edge to the midsole 206 medial edge.
- An average angle of sipe 212 k ′/ 212 l relative to axis A 21 can be found by drawing a line between the sipe 212 k ′/ 212 l endpoints and determining the angle of that line relative to axis A 21 . This is also shown in FIG. 2H , where line C 21 creates an angle b 23 in the lateral rear quadrant of the intersection with axis A 21 .
- a similar average angle could be defined for sipe 212 m. Because sipe 212 m is straight, however, that average angle would effectively be same as the angle of sipe 212 m itself relative to axis A 21 .
- rearwardly-angled mediolateral sipes 212 l through 212 o are located in a region that extends from the heads of metatarsals 3 , 7 , 11 , 15 and 19 to medial cuneiform 20 , navicular 23 and cuboid 24 .
- the presence of mediolateral rearwardly-angled sipes in this region offers several advantages.
- these sipes allow beneficial transtarsal motion during linear wearer motion (e.g., while running)
- these mediolateral rearwardly-angled sipes accommodate relative motion of the wearer tarsal bones (cuneiforms 19 - 21 , navicular 22 , cuboid 24 , talus 25 and calcaneus 26 ) that naturally occurs during unshod running on grass. This in turn allows the forefoot to more easily rotate relative to the midfoot about axis A 22 .
- the combination of sipes 212 l through 212 o with sipes having locations such as those of sipes 212 a through 212 k and 212 p through 212 r further improves the ability of sole structure 202 to facilitate natural foot motion.
- the average angles of one or more rearwardly-angled mediolateral sipes in a midfoot region, relative to a longitudinal axis such as axis A 21 and determined in a lateral rear quadrant (e.g., angle b 23 ), are between approximately 45 degrees and approximately 70 degrees.
- rearwardly-angled mediolateral sipes are spaced approximately 10 mm apart. This spacing may vary in some embodiments by, e.g., 5 mm to 20 mm and need not be constant for a set of mediolateral midfoot sipes.
- the average angles of multiple rearwardly-angled mediolateral midfoot sipes relative to a longitudinal axis need not be the same.
- one such sipe may form a first average angle relative to a longitudinal axis
- a second such sipe may form a second average angle relative to the longitudinal axis
- a third such sipe may form a third average angle relative to a longitudinal axis
- the first, second and third average angles may all be different from one another, but each may be within the range of approximately 45 degrees to approximately 70 degrees.

Abstract
A footwear sole structure may include a plurality of discrete sole elements defined by a plurality of sipes. The sipes may include a plurality of sipes that extend in a direction extending from a medial side of the sole structure to a lateral side of the sole structure and be rearwardly angled. Those sipes may be located in a midfoot region. The sole structure may include a plurality of additional sipes having longitudinal, transverse and other orientations.
Description
- This application claims priority to U.S. provisional patent application Ser. No. 61/632,837, titled “Articulated Sole Structure with Rearwardly Angled Mediolateral Midfoot Sipes” and filed Dec. 15, 2011. Provisional patent application 61/632,837, in its entirety, is incorporated by reference herein.
- Conventional articles of footwear often include two primary components: an upper and a sole structure. The upper provides a covering for the foot and securely positions the foot relative to the sole structure. The sole structure is secured to a lower surface of the upper and configured so as to be positioned between the foot and the ground when a wearer is standing, walking or running Sole structures are often designed so as to cushion, protect and support the foot. Sole structures may also be designed so as to increase traction and to help control potentially harmful foot motion such as overpronation.
- Many types of athletic footwear have a sole structure that includes a deformable midsole. A primary element of many conventional midsoles is a resilient polymer foam material that extends throughout the length of the footwear. The physical characteristics a midsole largely depend on the density and other properties of the polymer foam material and on the dimensional configuration of the midsole. By varying these factors throughout the midsole, the relative stiffness, degree of ground reaction force attenuation, and energy absorption properties may be altered to meet the specific demands of the activity for which the footwear is intended to be used.
- Commonly-owned U.S. Pat. No. 6,990,755 describes an article of footwear having an articulated sole structure in which multiple sipes separate discrete sole elements of the midsole. The resulting sole structure helps to simulate a sensation of barefoot running while at the same time providing a degree of cushioning and protection to the wearer foot. The motion of a human foot during running and other activities can be quite complex, however. Accordingly, there remains an ongoing need for improved articulated sole structures that better accommodate natural tendencies and kinematics of the human foot.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the invention.
- In at least some embodiments, a footwear sole structure may include a plurality of discrete sole elements defined by a plurality of sipes. The sipes may include a plurality of sipes that extend in a direction extending from a medial side of the sole structure to a lateral side of the sole structure (i.e., a mediolateral direction) and be rearwardly angled. The rearwardly-angled mediolateral sipes may be located in a midfoot region. The sole structure may include a plurality of additional sipes having longitudinal, transverse and/or other orientations.
- Some embodiments are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings and in which like reference numerals refer to similar elements.

The sole structures depicted in the figures and discussed below have configurations that are suitable for athletic activities such as running Other embodiments include sole structures and footwear having one or more features of the herein-described sole structures and adapted for basketball, baseball, football, soccer, walking, hiking and other athletic and nonathletic activities. Persons skilled in the relevant art will thus recognize that concepts disclosed herein may be applied to a wide range of footwear styles and are not limited to the specific embodiments discussed below and depicted in the figures.
- To assist and clarify subsequent description of various embodiments, various terms are defined herein. Unless context indicates otherwise, the following definitions apply throughout this specification (including the claims). “Shoe” and “article of footwear” are used interchangeably to refer to articles intended for wear on a human foot. A shoe may or may not enclose the entire foot of a wearer. For example, a shoe could include a sandal or other article that exposes large portions of a wearing foot. The “interior” of a shoe refers to space that is occupied by a wearer's foot when the shoe is worn. An “interior side” (or surface) of a shoe element refers to a face of that element that is (or will be) oriented toward the shoe interior in a completed shoe. An “exterior side” (or surface) of an element refers to a face of that element that is (or will be) oriented away from the shoe interior in the completed shoe. In some cases, the interior side of an element may have other elements between that interior side and the interior in the completed shoe. Similarly, an exterior side of an element may have other elements between that exterior side and the space external to the completed shoe.
- Shoe elements can be described based on regions and/or anatomical structures of a human foot wearing that shoe, and by assuming that shoe is properly sized for the wearing foot.
FIG. 1 shows outlines of human foot bones from a plantar (bottom) view. Those bones are the firstdistal phalanx 1, the firstproximal phalanx 2, thefirst metatarsal 3, the seconddistal phalanx 4, the secondmiddle phalanx 5, the secondproximal phalanx 6, thesecond metatarsal 7, the third distal phalanx 8, the third middle phalanx 9, the thirdproximal phalanx 10, thethird metatarsal 11, the fourthdistal phalanx 12, the fourthmiddle phalanx 13, the fourthproximal phalanx 14, thefourth metatarsal 15, the fifth distal phalanx 16, the fifth middle phalanx 17, the fifthproximal phalanx 18, thefifth metatarsal 19, themedial cuneiform 20, theintermediate cuneiform 21, thelateral cuneiform 22, thenavicular 23, the cuboid 24, thetalus 25 and thecalcaneus 26. The exact shape and size of the bones in a foot will vary from individual to individual, andFIG. 1 is merely intended as a convenient general reference. - A forefoot region of a foot includes the
metatarsals phalanges navicular 23 and cuneiforms 20-22, as well as the heads of themetatarsals talus 25 andcalcaneus 26. A hindfoot element of a sole structure is an element having one or more portions located under, to the lateral and/or medial side of, and/or behind a wearer's hindfoot (or portion thereof) when the shoe is worn. The forefoot region may overlap with the midfoot region, as may the midfoot and hindfoot regions. - Unless indicated otherwise, a longitudinal axis refers to a horizontal heel-toe axis along the center of the foot, while that foot is resting on a horizontal surface, that is roughly parallel to a line along the second metatarsal and second phalanges. A transverse axis refers to a horizontal axis across the foot that is generally perpendicular to a longitudinal axis. A longitudinal direction is parallel (or roughly parallel) to a longitudinal axis. A transverse direction is parallel (or roughly parallel) to a transverse axis.

Aninsole 205 can be positioned adjacent to the top surface oflasting element 203 withininterior 215.Insole 205 may contact the bare or socked plantar surface of the wearer foot along the entire length of the foot.Insole 205 may be compressible and/or have an orthotic shape to conform to a wearer foot. - In the embodiment of
shoe 200,sole structure 202 primarily comprises a single-piece midsole 206. Atop surface 207 ofmidsole 206 is bonded to the underside oflasting element 203 and to borderportions 214 of upper 201 located outside ofseam 204.Midsole 206 protects the foot of ashoe 200 wearer from ground surface material that might puncture or otherwise injure the skin on the underside of the foot.Midsole 206 also provides cushioning by attenuating ground reaction forces and absorbing energy when a wearer ofshoe 200 walks or runs. Suitable materials formidsole 206 can include any of various polymer foams utilized in conventional footwear midsoles, including but not limited to ethylvinylacetate (EVA), thermoplastic polyurethane (TPU) and polyurethane foams.Midsole 206 may also be formed from a relatively lightweight polyurethane foam having a specific gravity of approximately 0.22, as manufactured by Bayer AG under the BAYFLEX trademark. -
Midsole 206 has an articulated structure that imparts relatively high flexibility and articulation. The flexible structure ofmidsole 206 is configured to complement the natural motion of the foot during running or other activities, and may impart a feeling or sensation of barefoot running In contrast with barefoot running, however,midsole 206 attenuates ground reaction forces and absorbs energy to cushion the foot and decrease the overall stress upon the foot. Moreover, and as described in further detail below,midsole 206 includes a plurality of midfoot sipes that accommodate transtarsal foot motion. - Referring to
FIGS. 2A and 2B ,midsole 206 includes a spanningportion 209 and an articulatedportion 210. The precise boundaries of spanningportion 209 and articulatedportion 210 are only approximately indicated inFIGS. 2A and 2B . Spanningportion 209 includes the portion ofmidsole 206 abovesipes 212. Articulatedportion 210 includes a plurality of discrete sole elements 211 defined bysipes 212. Sole elements 211 are connected to and extend downward from spanningportion 209. Only the ends ofcertain sipes 212 and a portion of sole elements 211 can be seen inFIGS. 2A through 2D . - All of
sipes 212 and sole elements 211 can be seen inFIG. 2G , a bottom view ofshoe 200 showing the exposed bottom surface ofsole structure 202. In the embodiment ofshoe 200,midsole 206 includes eighteensipes 212 a through 212 r.Sipes 212 a through 212 r define numerous discrete sole elements 211 by exposing sides of those elements. This permits those discrete elements to move away from one another and allowsmidsole 206 to flex alongsipes 212. For example, a medial side ofsole element 211 a is exposed bysipe 212 a. A lateral side ofsole element 211 a is exposed bysipe 212 b. Front and rear sides ofsole element 211 a are exposed bysipes 212 h and 212 i, respectively. The exposed sides ofsole element 211 a allowsole element 211 a to separate from the sides of adjacent sole elements when a wearer steps on an uneven surface and/or when the wearer dorsiflexes, pronates, supinates or otherwise moves his or her foot. Other sole elements can similarly separate from adjacent sole elements. To avoid clutteringFIG. 2G with unnecessary details, only a few of sole elements 211 are marked or discussed. - As used herein, a sipe generally refers to a separation between sides of adjacent discrete sole elements. In some cases, a sipe may leave little or no space between the sides of adjacent sole elements when the siped sole structure is unloaded. For example, side faces of adjacent sole elements separated by a narrow sipe may actually be in contact with one another when the sole structure is unloaded, and there may only be space between those faces when the sole structure flexes along the sipe. In other cases, a wider sipe may create a larger gap between sides of adjacent sole elements, and there may be space between those sole element sides in the unloaded sole structure. In still other cases, a sipe may have a portion (e.g., the deepest part of the sipe) in which adjacent sole elements are in contact when the sole structure is unloaded and another portion (e.g., the portion of the sipe near the bottom surface of the sole structure) in which there is a groove or other space between adjacent sole element faces in the unloaded sole structure.
- Sipes can be formed by molding, e.g., by including blades in a midsole mold corresponding to desired sipe locations. Sipes can also be formed by cutting sipes in a midsole or other sole structure using a knife or other tool. Sipes can also be formed using combinations of molding and cutting operations, as well as by other processes. In some embodiments, thinner sipes may be “knifed” (i.e., cutting with a blade), while wider sipes may be molded into a midsole. In some such embodiments, the molded-in sipes may be located in areas of a shoe where higher stresses may be expected (e.g., at the heel, where a step lands, and at the toe, where step-off occurs). Molded-in sipes may in some cases be more durable than knifed sipes, as all sides of the sipe are exposed to curing conditions and have an outer crust of cured polymer. Conversely, knifed sipes are cut into the midsole after curing. Thus, knifed sipes side edges and their junction with the spanning portion may constitute uncured polymer material that is less durable than cured polymer.
- As seen in
FIG. 2G ,sipes Sipe 212 a is located in the medial forefoot region and extends fromforefoot sipe 212 f tomidfoot sipe 212 k.Sipe 212 b is curved and extends from a front edge ofoutsole 206 in the toe region tohindfoot sipe 212 r.Sipe 212 c is also curved and extends from the front edge ofoutsole 206 to a rear edge ofoutsole 206 in the hindfoot region.Sipe 212 d is curved and extends fromforefoot sipe 212 e tohindfoot sipe 212 r. -
Sipes 212 e through 212 r are transversely oriented and extend in generally transverse directions.Sipe 212 e extends from a lateral edge ofoutsole 206 tosipe 212 b.Sipes 212 f through 212 k,sipe 212 m,sipe 212 q andsipe 212 r extend from the lateral edge ofmidsole 206 to the medial edge ofoutsole 206.Sipe 2121 extends from themidsole 206 lateral edge to the intersection ofsipes Sipe 212 n extends from themidsole 206 medial edge tosipe 212 b. Sipe 212 o extends from themidsole 206 lateral edge tosipe 212 c.Sipe 212 p extends from themidsole 206 medial edge to the intersection ofsipes 212 d and 212 o. Although sipe 212 l joinssipe 212 k just short of reaching themidsole 206 medial edge, sipe 212 l and theportion 212 k′ ofsipe 212 k to the medial side ofsipe 212 a effectively form a single sipe that extends from themidsole 206 lateral edge to themidsole 206 medial edge. - In some embodiments, sipe depth (as a percentage of sole structure thickness) is maximized and the thickness of a spanning portion minimized so as to reduce the force needed to flex the sole structure along the sipe and to separate adjacent sole elements. For example, and as seen in the area cross-sectional view of
FIG. 2F , the thickness t of spanningportion 209 oversipe 212 q under the footbed is relatively small compared to the depth d ofsipe 212 q. To avoid confusingFIG. 2F with unneeded detail, longitudinally-orientedsipes sipe 212 q. Similarly,sipes 212 a through 212 d have been omitted from the area cross-sectional view ofFIG. 2E . - Sipe depth d and under-footbed spanning portion thickness t may vary within a particular shoe and among various embodiments. In at least some embodiments, the portions of
midsole 209 abovesipes 212 and sole elements 211 and under the footbed have a thickness t of about 3 mm throughout the entire midsole. In some embodiments, this thickness t may be in a range between about 2.5 mm and about 10 mm. Other embodiments include, without limitation: embodiments in which this thickness t is in a range between about 3 mm and about 8 mm, embodiments in which this thickness t is in a range between about 3 mm and about 6 mm, embodiments in which this thickness t is in a range between about 3 mm and about 5 mm, embodiments in which this thickness t is in a range between 3 mm and about 4 mm, and embodiments in which this thickness t is in a range between about 2.5 mm and about 3.5 mm. - For men's U.S. shoe sizes according to some embodiments, sipe depth d in the hindfoot region (near the midsole edge) is about 18 mm +/−3 mm, sipe depth d in the midfoot region (near the midsole edge) is about 14 mm +/−3 mm, and sipe depth d in the forefoot region (near the midsole edge) is about 10 mm +/−3 mm. Sipe depths d may decrease by, e.g., about 30% or more in the middle of the sipe. For men's U.S. shoe sizes according to some additional embodiments, sipe depths d are similar, but may be within a different range (e.g., +/−2 mm). In any of these embodiments, the thickness t of the midsole under-footbed spanning portion above the sipes may have a value of about 3 mm, may have a value in one the ranges previously indicated, or may have a different value.
- For women's U.S. shoe sizes according to some embodiments, sipe depth d in the hindfoot region (near the midsole edge) is about 17 mm +/−3 mm, sipe depth d in the midfoot region (near the midsole edge) is about 13 mm +/−3 mm, and sipe depth d in the forefoot region (near the midsole edge) is about 9 mm +/−3 mm. Sipe depths d may decrease by, e.g., about 30% or more in the middle of the sipe. For women's U.S. shoe sizes according to some additional embodiments, sipe depths d are similar, but may be within a different range (e.g., +/−2 mm). In any of these embodiments, the thickness t of the midsole under-footbed spanning portion above the sipes may have a value of about 3 mm, may have a value in one the ranges previously indicated, or may have a different value.
- In some embodiments, and as to some or all of the sipes located in the hindfoot and midfoot regions, a ratio d/t is at least 1 over the majority of the length of those sipes. This may include, without limitation, sipes 212 l through 212 o. The ratio d/t over a majority of a sipe length may be greater (e.g., 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, etc.) for some or all sipes in the hindfoot and/or midfoot regions (including but not limited to sipes 212 l through 212 o). Additional embodiments can include, without limitation, one or more of the following features: the d/t ratio in some or all hindfoot region sipes can be anywhere in a range between about 8.4 to about 1.5 for men's U.S. sizes, the d/t ratio in some or all hindfoot region sipes can be anywhere in a range between about 6 to about 4.2 for men's U.S. sizes, the d/t ratio in some or all midfoot region sipes can be anywhere in a range between about 6.8 to about 1.1 for men's U.S. sizes, the d/t ratio in some or all midfoot region sipes can be anywhere in a range between about 5.7 to about 4 for men's U.S. sizes, the d/t ratio in some or all midfoot region sipes be anywhere in a range between about 5.3 to about 3.7 for men's U.S. sizes, the d/t ratio in some or all midfoot region sipes be anywhere in a range between about 4.7 to about 3.3 for men's U.S. sizes, the d/t ratio in some or all hindfoot region sipes can be anywhere in a range between about 8 to about 1.4 for women's U.S. sizes, the d/t ratio in some or all hindfoot region sipes can be anywhere in a range between about 5.7 to about 4 for women's U.S. sizes, the d/t ratio in some or all midfoot region sipes can be anywhere in a range between about 6.4 to about 1 for women's U.S. sizes, the d/t ratio in some or all midfoot region sipes can be anywhere in a range between about 4.3 to about 3 for women's U.S. sizes, the d/t ratio in some or all hindfoot region sipes can be at least 2 over at least 50% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 2 over at least 75% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 2 over at least 90% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 2.5 over at least 50% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 2.5 over at least 75% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 2.5 over at least 90% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 3 over at least 50% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 3 over at least 75% of the length of those sipes, the d/t ratio in some or all hindfoot region sipes can be at least 3 over at least 90% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 2 over at least 50% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 2 over at least 75% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 2 over at least 90% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 2.5 over at least 50% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 2.5 over at least 75% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 2.5 over at least 90% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 3 over at least 50% of the length of those sipes, the d/t ratio in some or all midfoot region sipes can be at least 3 over at least 75% of the length of those sipes, and/or the d/t ratio in some or all midfoot region sipes can be at least 3 over at least 90% of the length of those sipes.
- In the embodiment of
shoe 200,sole structure 202 includes a spanningportion 209 and an articulatedportion 210 as parts of a single integrally-formed midsole. Spanningportion 209 interconnects the discrete sole elements defined by the sipes of the articulated portion. This need not be the case, however. In some embodiments, for example, a lasting element or some other flexible member coupled to the underside of a lasting element may serve as a sole structure spanning portion. Individual sole elements could be cut or otherwise formed and then bonded to the bottom of that lasting element or other flexible member. In such an embodiment, the thickness t of the spanning portion could be the thickness of the flexible member bonded to the bottom of the lasting element. If the sole elements are bonded directly to the lasting element, t could equal zero. - As also seen in
FIG. 2G , various tread patterns may be formed in the exposed surfaces ofsole elements 212. Tread patterns other than those shown inFIG. 2G could be used. One or more discrete sole elements 211 may further include anoutsole element 208 embedded in or otherwise secured to its lower surface. Such outsole elements may provide increased wear resistance and/or be included for aesthetic purposes. Anoutsole element 208 may be recessed within a sole element 211. In some embodiments,outsole elements 208 may extend throughout all or substantially all of the lower surface of midsole 206 (i.e., each sole element may have an attached outsole element). In the embodiment ofshoe 200,outsole elements 208 are located onsole elements sole elements outsole elements 208 can include any of various conventional rubber materials utilized in footwear outsoles (e.g., carbon black rubber compound). -
FIG. 2H is another bottom view ofshoe 206 showing the exposed bottom surface ofsole structure 202. The foot bone outlines ofFIG. 1 are superimposed inFIG. 2H so as to indicate the approximate locations, relative tosipes 212 and sole elements 211, of the bones in a wearer foot located withininterior 215. For convenience,outsole elements 208 have been omitted. A longitudinal axis A21 ofsole structure 202 is generally parallel to a line that follows the second phalanges 4-6 and thesecond metatarsal 7. In the embodiment ofoutsole 206,transverse sipes transverse sipes 212 e through 212 j is oriented in a medial-to-lateral (i.e., mediolateral) direction and is forwardly angled. Thus, the angles in the forward lateral quadrants of the intersections ofsipes 212 e through 212 j with axis A21 (e.g., angle b21) are less than 90 degrees. - Conversely, each of sipes 212 l through 212 o is oriented in a mediolateral direction and is rearwardly angled. Angles in the forward medial quadrants of the intersections of sipes 212 l through 212 o with axis A21 (e.g., angle b22) are thus less than 90 degrees, as are angles in the rear lateral quadrants of such intersections. As indicated above, sipe 212 l and
sipe portion 212 k′ effectively form a single sipe that extends from themidsole 206 lateral edge to themidsole 206 medial edge. An average angle ofsipe 212 k′/212 l relative to axis A21 can be found by drawing a line between thesipe 212 k′/212 l endpoints and determining the angle of that line relative to axis A21. This is also shown inFIG. 2H , where line C21 creates an angle b23 in the lateral rear quadrant of the intersection with axis A21. A similar average angle could be defined forsipe 212 m. Becausesipe 212 m is straight, however, that average angle would effectively be same as the angle ofsipe 212 m itself relative to axis A21. - As further seen in
FIG. 2H , rearwardly-angled mediolateral sipes 212 l through 212 o are located in a region that extends from the heads ofmetatarsals medial cuneiform 20,navicular 23 andcuboid 24. The presence of mediolateral rearwardly-angled sipes in this region offers several advantages. For example, these sipes allow beneficial transtarsal motion during linear wearer motion (e.g., while running) In particular, these mediolateral rearwardly-angled sipes accommodate relative motion of the wearer tarsal bones (cuneiforms 19-21,navicular 22, cuboid 24,talus 25 and calcaneus 26) that naturally occurs during unshod running on grass. This in turn allows the forefoot to more easily rotate relative to the midfoot about axis A22. The combination of sipes 212 l through 212 o with sipes having locations such as those ofsipes 212 a through 212 k and 212 p through 212 r further improves the ability ofsole structure 202 to facilitate natural foot motion. - In at least some embodiments, the average angles of one or more rearwardly-angled mediolateral sipes in a midfoot region, relative to a longitudinal axis such as axis A21 and determined in a lateral rear quadrant (e.g., angle b23), are between approximately 45 degrees and approximately 70 degrees. In some embodiments, rearwardly-angled mediolateral sipes are spaced approximately 10 mm apart. This spacing may vary in some embodiments by, e.g., 5 mm to 20 mm and need not be constant for a set of mediolateral midfoot sipes. The average angles of multiple rearwardly-angled mediolateral midfoot sipes relative to a longitudinal axis need not be the same. For example, one such sipe may form a first average angle relative to a longitudinal axis, a second such sipe may form a second average angle relative to the longitudinal axis, a third such sipe may form a third average angle relative to a longitudinal axis, etc. The first, second and third average angles may all be different from one another, but each may be within the range of approximately 45 degrees to approximately 70 degrees.

Those sole elements are connected to and extend downward from spanningportion 309. Only the ends ofcertain sipes 312 and certain sole elements can be seen inFIGS. 3A through 3D . - All of
sipes 312 and all sole elements can be seen inFIG. 3E , a bottom view ofshoe 300 showing the exposed bottom surface ofsole structure 302. In the embodiment ofshoe 300,outsole 306 includes eighteensipes 312 a through 312 r. Similar tomidsole 206,sipes 312 a through 312 r define numerous discrete sole elements inmidsole 306.Sipes Sipe 312 a is located in the medial forefoot region and extends fromforefoot sipe 312 g to midfoot sipe 312 l.Sipe 312 b is curved and extends from a front edge ofoutsole 306 in the toe region to a rear edge ofoutsole 306 in the hindfoot region.Sipe 312 c is curved and extends fromforefoot sipe 312 e tohindfoot sipe 312 p.Sipe 312 d is curved and extends fromforefoot sipe 312 g to the rear edge ofoutsole 306 in the hindfoot region.Sipes 312 e through 312 r are transversely oriented and extend from a medial edge ofmidsole 306 to a lateral edge ofmidsole 306. - Various tread patterns may be formed in the exposed surfaces of discrete sole elements in
midsole 306. Tread patterns other than those shown inFIG. 3E could be used. One or more discrete sole elements may further include anoutsole element 308 embedded in or otherwise secured to its lower surface. In the embodiment ofshoe 300,outsole elements 308 are located on sole elements in the hindfoot region and in sole elements in the forefoot region. In some embodiments,outsole elements 308 may extend throughout all or substantially all of the lower surface of midsole 306 (i.e., each sole element may have an attached outsole element). Suitable materials foroutsole elements 308 can include those indicated above foroutsole elements 208. -
FIG. 3F is another bottom view ofshoe 300 showing the exposed bottom surface ofsole structure 302. The foot bone outlines ofFIG. 1 are superimposed inFIG. 3F so as to indicate the approximate locations, relative tosipes 312, of the bones in a wearer foot located within an interior ofshoe 300. For convenience,outsole elements 308 have been omitted. A longitudinal axis A31 ofsole structure 302 is generally parallel to a line that follows the second phalanges 4-6 and thesecond metatarsal 7. In the embodiment ofoutsole 306,transverse sipes transverse sipes 312 e through 312 i is oriented in a mediolateral direction and is forwardly angled. - Each of sipes 312 l through 312 o is curved and has two concave portions. Specifically, each of sipes 312 l through 312 o has a rearwardly-facing concave portion on the medial side and a forwardly-facing concave portion on the lateral side (or conversely, a forwardly-facing convex portion on the medial side and a rearwardly-facing convex portion on the lateral side). Notwithstanding its curved shape, however, each of sipes 312 l through 312 o is nonetheless oriented in a mediolateral direction and is rearwardly angled.
FIG. 3F shows a broken line C31 connecting the end ofsipe 3121 at the medial edge ofmidsole 306 with the end ofsipe 3121 at the lateral edge ofmidsole 306. Similar lines C32, C33 and C34 are shown connecting the medial and lateral ends ofsipes 312 m through 312 o, respectively. As can be seen by comparing each of lines C31 through C34 with longitudinal axis A31, the average angles of sipes 312 l through 312 o relative to axis A31 in the lateral rear quadrant (e.g., angle b31) are all less than 90 degrees. In at least some embodiments, each of angle b31 and the similarly defined angles of each of lines C32 through C34 relative to axis A31 is between approximately 45 degrees and approximately 70 degrees. Sipes 312 l through 312 o are, in at least some embodiments, approximately 10 mm apart. - In some embodiments, shoes such as or similar to those described in connection with

midsole 206, mediolateral rearwardly-angled sipes 312 l through 312 o allow beneficial transtarsal motion during linear wearer movement. The combination of sipes 312 l through 312 o with sipes having locations such as those ofsipes 312 a through 312 k and 312 p through 312 r further improves the ability ofsole structure 302 to facilitate natural foot motion. -

Various tread patterns may be formed in the exposed surfaces of discrete sole elements inmidsole 406. Tread patterns other than those shown inFIG. 4E could be used. One or more discrete sole elements may further include anoutsole element 408 embedded in or otherwise secured to its lower surface. In the embodiment ofshoe 400,outsole elements 408 are located on sole elements in the hindfoot region and in sole elements in the forefoot region. In some embodiments,outsole elements 408 may extend throughout all or substantially all of the lower surface of midsole 406 (i.e., each sole element may have an attached outsole element). Suitable materials foroutsole elements 408 can include those indicated above foroutsole elements 208. -
Midsole 406 includes areverse flex groove 420 in the lower portion ofsipe 412 c.Groove 420 accommodates reverse flexing of the foot in the longitudinal direction. In some embodiments,groove 420 includes a wider outer portion and a deeper sipe that extends upward into the midsole beyond the bottom of the wider outer portion. In some embodiments, the wider outer portion has a curved (e.g., rounded) outer surface, is approximately 3 mm to 4 mm wide, and is approximately 2 mm to 4 mm deep. -
FIG. 4F is another bottom view ofshoe 400 showing the exposed bottom surface ofsole structure 402. The foot bone outlines ofFIG. 1 are superimposed inFIG. 4F so as to indicate the approximate locations, relative tosipes 412, of the bones in a wearer foot located within an interior ofshoe 400. A longitudinal axis A41 ofsole structure 402 is generally parallel to a line that follows the second phalanges 4-6 and thesecond metatarsal 7.Outsole elements 408 have been omitted. Sipes 412 l through 412 o are similar to sipes 312 l through 312 o. Lines (e.g., line D41) connecting the ends of sipes 412 l through 412 o form angles with longitudinal axis A41 in the lateral rear quadrant (e.g., angle b41) of approximately 45 degrees to approximately 70 degrees. Sipes 412 l through 412 o are curved in a manner similar to sipes 312 l through sipes 312 o, but are somewhat wider. - Similar to sipes 212 l through 212 o discussed in connection with
midsole 206, mediolateral rearwardly-angled sipes 412 l through 412 o allow beneficial transtarsal motion during linear wearer movement. The combination of sipes 412 l through 412 o with sipes having locations such as those ofsipes 412 a through 412 k and 412 p through 412 r further improves the ability ofsole structure 402 to facilitate natural foot motion. - In some embodiments, shoes such as or similar to those described in connection with

FIG. 5F is another bottom view ofshoe 500 showing the exposed bottom surface ofsole structure 502. The foot bone outlines ofFIG. 1 are superimposed inFIG. 5F so as to indicate the approximate locations, relative tosipes 512, of the bones in a wearer foot located within an interior ofshoe 500. For convenience,outsole elements 508 have been omitted. A longitudinal axis A51 ofsole structure 502 is generally parallel to a line that follows the second phalanges 4-6 and thesecond metatarsal 7. Sipes 512 l through 512 m are curved similar to sipes 312 l through 312 m. Lines (e.g., line E51) connecting the ends of sipes 512 l through 512 m form angles with longitudinal axis A51 in the lateral rear quadrant (e.g., angle b51) of approximately 45 degrees to approximately 70 degrees. - Similar to sipes 212 l through 212 m discussed in connection with
midsole 206, mediolateral rearwardly-angled sipes 512 l through 512 m allow beneficial transtarsal motion during linear wearer motion. The combination of sipes 512 l through 512 n with sipes having locations such as those ofsipes 512 a through 512 k and 512 p through 512 s further improves the ability ofsole structure 502 to facilitate natural foot motion. - In some embodiments, shoes such as or similar to those described in connection with
FIGS. 5A-5F have d dimensions such as are described in connection with previous embodiments for some or all sipes, and/or t dimensions such as are described in connection with previous embodiments for some or all midsole portions, and/or d/t ratios such as are described in connection with previous embodiments for some or all midsole portions. - The number and configuration of rearwardly angled mediolateral midfoot sipes can be varied. As indicated above, the rearward angle of such sipes may range, e.g., between about 45 degrees and about 70 degrees, measured relative to a longitudinal axis and in a rear lateral quadrant of an intersection of the sipe with that axis. Some embodiments may include five or more rearwardly angled mediolateral midfoot sipes. Curvatures other than those shown in the drawings could be utilized, but with the sipe endpoints still achieving a rearward angle between about 45 degrees and about 70 degrees. The distances between sipes could vary and need not be uniform. Sipe angles need not be uniform. Sipe gap (e.g., whether the sipe is like sipe 312 l of
FIG. 3E or like sipe 412 l ofFIG. 4E ) need not be uniform within a set of sipes in a single midsole. - In still further embodiments, a sole structure and/or article of footwear may include additional features. For example, in some embodiments a sole structure may include stiffening elements in one or more regions and/or additional padding in one or more regions. A lasting element could include an incorporated padding element. The depths, orientations and number of sipes may be varied.
