Definitions
- the present invention relates to an orthotic insole.
- the human foot is a complex anatomical structure, responsible for bearing weight and enabling balance and locomotion. Tendons in the lower leg and foot work together to form an upward curve or arch in the centre of the foot. When the tendons do not work together properly, the arch flattens, causing a condition known as flat foot or fallen arch. This can result in a lack of stability when standing, and can lead to straining of the ligaments under the feet as well as problems throughout the leg and lower back. To compensate and correct for this, orthotic insoles can be placed in footwear to support the underside of the foot and prevent the arch flattening as a user stands and moves.
- Rigid and firm orthotics assist in retaining feet in an anatomically desirable state when stationary, but they do not assist the natural foot function as they can inhibit the arches in performing their natural spring-like action when a user is walking, running or jumping.
- Natural foot function involves a spring like action through the arches, which not only acts to absorb shock, but also stimulates proprioceptive nerve fibers that provide information to the brain, critical for both stability and agility.

- The human foot is a complex anatomical structure, responsible for bearing weight and enabling balance and locomotion. Tendons in the lower leg and foot work together to form an upward curve or arch in the centre of the foot. When the tendons do not work together properly, the arch flattens, causing a condition known as flat foot or fallen arch. This can result in a lack of stability when standing, and can lead to straining of the ligaments under the feet as well as problems throughout the leg and lower back. To compensate and correct for this, orthotic insoles can be placed in footwear to support the underside of the foot and prevent the arch flattening as a user stands and moves. Rigid and firm orthotics assist in retaining feet in an anatomically desirable state when stationary, but they do not assist the natural foot function as they can inhibit the arches in performing their natural spring-like action when a user is walking, running or jumping. Natural foot function involves a spring like action through the arches, which not only acts to absorb shock, but also stimulates proprioceptive nerve fibers that provide information to the brain, critical for both stability and agility.

- Notwithstanding any other forms which may fall within the scope of the present invention, preferred embodiments of the present invention will now be described, by way of examples only, with reference to the accompanying drawings in which:
-
FIG. 1 a shows a schematic view from directly below of the positions of the arches in a typical left foot; line A-B showing the anterior transverse arch, line B-C showing the lateral longitudinal arch, and line A-C showing the medial longitudinal arch. -
FIG. 1 b shows a schematic view of the foot ofFIG. 1 a viewed from the side. -
FIG. 2 shows a top plan view of a pair of orthotic footwear insoles side by side according to an embodiment of the invention. -
FIG. 3 shows another top plan view of the pair of orthotic footwear insoles in another relative orientation. -
FIG. 4 is a side perspective view of a right foot orthotic insole. - It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
- In the description below, ‘outer’ and ‘inner’ are used to refer to the sides of the insole relative to one foot of a pair of feet: the side adjacent to or closest to the other foot when a person is standing with their feet together is the inner side, and the other or opposite side of the same insole is the outer side. “Outer” corresponds to the anatomical lateral aspect of the foot whilst “inner” corresponds to the anatomical medial aspect of the foot. These terms are not intended to apply as they would to a single insole in isolation, where the ‘outer edge’ would be the entire perimeter and the ‘inner portion’ or part would be anything inside this perimeter.
-
FIGS. 2 and 3 shows a pair of orthotic insoles 1 according to a first embodiment of the present invention, the pair comprising aleft insole 1 a and aright insole 1 b.FIG. 4 shows theright insole 1 b. Each orthotic insole 1 has amain body portion 2 shaped and sized to fit inside and rest against the upper surface of the sole of an item of footwear. Each of theorthotic insoles - For ladies shoes, ¾ length orthotic insoles are designed for open shoes or heels. The orthotic insole is placed in contact with the upper surface of the sole of the shoe. It fits from the heel to ¾ of the length of the sole and is held in place by a hook and loops (Velcro) tab under the heel section of the orthotic.
- The medial arch A-C runs along the instep of the foot (from the calcaneus, the talus, the navicular, the three cuneiforms, and the first, second, and third metatarsals). The lateral arch A-B runs along the outside of the foot (calcaneus, the cuboid, and the fourth and fifth metatarsals). The anterior arch B-C supports under the middle three toes at their base (cuneiforms, cuboid and the second, third and fourth metatarsals). The purpose of the arches is to provide stability whilst standing, and the ability to absorb stress whilst walking, running and jumping in a similar manner to a shock absorber, as well as providing valuable neurological input.
- The orthotic insole 1 is formed as a unitary item from a material of a particular density (or from an assembled layers of materials) that provides the necessary support for the foot and particularly the medial, lateral and anterior arches of the mid-foot, while providing shock absorption in such a manner that the
body 2 of the orthotic insole 1 works with this process, flexing and rebounding as weight is transferred through the foot during movement such as walking and running, rather than merely supporting the arch or arches in the correct position when stationary as in prior art insoles. - The orthotic insole 1 has three arch support zones: medial
arch support zone 4, lateralarch support zone 5, and anteriorarch support zone 6. These are shaped, and spaced over the top surface of theinsole body 2, in a manner that offers maximum or additional support when standing and during the full gait cycle, over and above that that would be provided by a non-contoured insert, or one contoured in a manner that does not provide specific support for all three arches. As well as support for the three mid-arches, support is provided for the heel (calcaneus) by aheel support zone 7, and for the first metatarsal head and phalangeal joint by ahead support zone 8, and abase support zone 9. - The medial
arch support zone 4 is formed on the orthotic insole 1 so that in use it will be located under the medial arch of a user's foot. That is, on the inner side of the orthotic insole 1 just in front of the heel. The medialarch support zone 4 appears as an upwardly curving arced bulge when viewed from the inner side of the orthotic insole 1. The medialarch support zone 4 has aninner face 4 a that has a lower edge generally coincident with the inner edge of the orthotic insole 1. Theinner face 4 a is substantially planar and slightly inwardly curved at each end (front andrear ends body 2, slightly towards the outer edge of thebody 2 when viewed from above the orthotic insole 1. Anouter face 4 b extends towards the outer edge of thebody 2 from thetop edge 4 c of theinner face 4 a. When viewed from above, theouter face 4 b appears as an outwardly curving arced bulge, thefront end 4 d of theouter face 4 b appearing elongated in comparison to therear end 4 e of theouter face 4 b. Theouter face 4 b is generally shaped as a curved mound. In other words, the medialarch support zone 4 in plan view has substantially the form of a letter “D” for theright insole 1 b and a reversed letter “D” for theleft insole 1 a, with the medialarch support zone 4 appearing as an upwardly arched bulge from perimeter edges thereof. - The lateral
arch support zone 5 is located on thebody 2 so that in use it will be under the lateral arch of a user's foot. When viewed from above, the lateralarch support zone 5 has a generally ovoid appearance, with a flattened outer edge generally coincident or adjacent with the outer edge of thebody 2. The front andrear ends arch support zone 5 are rounded, and from above, the inner edge of the lateralarch support zone 5 curves towards the outer edge of thebody 2. From the side, the lateralarch support zone 5 curves upwards so that the overall appearance is smoothly domed. From above, the lateralarch support zone 5 can be regarded as generally kidney or oval shaped. A curved ridge is provided between the medialarch support zone 4 and the lateralarch support zone 5. - The anterior
arch support zone 6 is located so that it extends forwards in the notch formed between the outer edge of thefront end 4 d of the medialarch support zone 4 and the inner edge of thefront end 5 a of the lateralarch support zone 5. The anteriorarch support zone 6 is close in to the medialarch support zone 4, with a gap between the anteriorarch support zone 6 and the lateralarch support zone 5. That is, generally below the anterior arch of a user's foot in use. From above, the anteriorarch support zone 6 has the form of an ovoid with the longer axis aligned substantially along or parallel with the longer, or front/rear axis of thebody 2. From the side, the lateralarch support zone 5 appears upwardly smoothly domed. Alternatively, the anteriorarch support zone 6 can be generally circular in plan view. - The
heel support zone 7 is located on thebody 2 so that it will be under the heel of a user when the sole 1 is in position for use. Theheel support zone 7 has a rear edge that is coincident with and which curves around with the curved rear edge of thebody 2. From above, thefront end 7 a of theheel support zone 7 forms a triangular point that extends closely alongside the outer edge of therear end 4 e of the medialarch support zone 4 and beside the inner edge of therear end 5 b of the lateralarch support zone 5, with a gap between the inner edge of therear end 5 b and the outer side of the triangular point of theheel support zone 7. The point of the triangle between the medialarch support zone 4 and the lateralarch support zone 5 is rounded. From the side, theheel support zone 7 appears as a raised area (raised above the main or lower part of the body 2), theheel support zone 7 is substantially flat-topped. - The
head support zone 8 and thebase support zone 9 are located on the upper surface of theinsole body 2 adjacent the inner edge towards the toe or front so that they will be located under the distal phalange of the big toe and the metatarso-phalangeal joint of a user in use. From above, thehead support zone 8 and thebase support zone 9 both appear substantially circular, and both appear as smooth upwardly extending domes when viewed from the side. Thehead support zone 8 and thebase support zone 9 are spaced from each other. - In terms of thickness, the
heel support zone 7 is the thickets, the medialarch support zone 4 is next in thickness, the anteriorarch support zone 6,head support zone 8 and thebase support zone 9 are then next in thickness, and the lateralarch support zone 5 is least in thickness. - The embodiments of the present invention provide multiple advantages over existing insoles:
-
- The three arch support system provides shock absorption in such a manner that the insole flexes and rebounds as weight is transferred through the foot during movement such as walking and running, rather than merely supporting the arch or arches in the correct position when stationary as in prior art insoles.
- The rebound or trampoline effect also increase stimulation of the proprioceptive nerves, enhancing brain stimulation throughout the gait cycle.
- As well as arch support, support is provided under the first metatarsal and first phalanx which helps support the foot during “toe off” (the final phase of gait), and along with the arch support system this helps to prevent the formation of bunions.
- The insoles help reduce stress on the plantar fascia so heel spurs and plantar fasciitis can be overcome more quickly and even prevented from occurring in the first place.
- Providing support during heel strike also helps with conditions such as heel spurs.
- The orthotic insole can also help prevent foot problems such as plantar fasciitis, heel spurs, Morten's neuroma and bunions.
- The orthotic insoles provides 6 zones of support designed to offer maximum support when standing and during the full gait cycle
- The orthotic insoles provides support for all three arches in the mid-foot.
- To help the foot overcome the stresses involved with standing, walking and running on hard surfaces such as concrete, wooden floors and tiles, the orthotic insoles provides support for the heel (calcaneus) as well as the first metatarsal head and base. Providing support during heel strike helps with conditions such as heel spurs, whilst the three arch support system helps reduce stress on the plantar fascia so heel spurs and plantar fasciitis can be overcome more quickly and even prevented from occurring in the first place. Having support under the first metatarsal helps support the foot during “toe off” (the final phase of gait), and along with the three arch support system they help to prevent the formation of bunions.
- The orthotic insoles are not designed to push or lift the arches up. They are designed to enhance the stability of the feet by not allowing the arches to collapse, whilst enhancing the spring like action of the arches through the trampoline like action of the supports whilst in motion.
- The orthotic insoles provides six zones of support providing proprioceptive facilitation. Zone 1 provides support and reduction of impact stress for the calcaneus.
Zones Zone 5 supports the first metatarso-phalangeal joint andzone 6 provides support for the distal phalange of the big toe. - The material chosen for the six zones of support are designed to be able to absorb shock from impact whilst also having good recoil properties to enhance the natural foot action during gait by providing a “trampoline effect”. This helps biomechanical function as well as proprioceptive neurological input to the brain.
