Abstract
ABSTRACT OF THE DISCLOSURE
An anti-skidding foot-wear for use on ice, comprising an outsole of resiliently collapsible material including an ice-engaging main portion and an upstanding lateral edge portion character-ized by the latter, having traction studs projecting from the upstanding lateral edge portion as well as from the ground-engaging main portion and arranged such that, upon collapse of the outsole, the traction studs of the upstanding lateral edge portion also tractively engage the ice surface on which the user stands, whereby, upon pre-dominant engagement of the upstanding lateral edge portion with the ice, the traction studs of the lateral edge portion will maintain adequate anti-skidding effect.

Description
FIELD OF THE [NVENTION
.
Thls invention relates to a foot-wear of the type made with an outsole particularly constructed for anti-skid characteristics on an ice surf~ce.
DESCRIPTION OF THE PRIOR ART
Foot-wears of the above type are descrlbed ~n applicant's Canadian Patent N 867,576 dated April 6, 1971 and Pater.t 1,Olf 743 dated September 6, 1977. They are characterized by a soft and resiliently-collapsible outsole havlng traction studs pro~ectiTIg from its ground-engaging main portion bue not Erom its lateral edge portion. This is done and useful in particular for shoes and boots to play broom ball games on ice. Those foot-wears provide good adherencc on the ice upon collapse of th~ outsole against the ice. The traction studs on the ground-engaging main portion thu~
tractively enga~e the ice. However, the collapse o the outsole also results in collapse of the lAteral edge portion into engagement with the ise. When the foot is set flat on the ground or ice, the traction studs of the mfiin portion are in good tractive engagement with the ice and they provide adequate antl-skidding.
However, it ha3 been noted that, when the foot i8 not flat on the ground or ice, the anti-skidding effect is substantiai]y reduced.
It is found thAt this occurs due to prevailing engag~ment of the non-studded lateral edge portion Against the ice, as compared t, th~, studded maln portion of the outsole upon par~icular coll~pse of the latter.
Such particular collapse may, for in~ta;nce, occur with foot movements such as starting, stopping, ~umplng, changes of directions and late~al stopping.
SUMMARY OF THE INYE~iTlON
It is ~ ~eneral object of the present inven'tion to provide an anti-skidding foot-wear of the above type that avoids the above-mentioned disadvantages.
It is a more specific object of the present invention to provlde an anti-skidding foot-wear of the above type, which is aLso effect-

DETAILED DESCRI~T ~I~ OF THE PREFERRED EMBODIMENTS
.
The anti~skidding foot-wear according to the embodiment of Figures 1, 2, and 3 comprises an outsole 10, made of resiiiently-collapsible material, such as soft rubber or resilient foam, closed or open-cell sponge rubber, microcellular rubber3 latex foam and plaatic foam. The outsole 10 is of sub3tantial thickness and includes an ice-engaging main sole portion 11 and an upstanding lateral edge portion 12 completely surrounding the foot-wear inclu~ve of the heel portion, toe portion and opposite sides. The rela~lvely thlc'.i ice-engaging main ~ole portion 11 is formed with a plurality of cavities 13 extending along a major portion of the thickness of the ice-en~aging main sole portion. The cavities 13 add to the softness of the outsole over and above the inherent softness of the material forming the outaole.
Traction studs 14, of uniform size and shspe, are integrally formed with the;~uc~ole 10 and outwardly project from the upstanding lateral edge portloll 12, as well as from the ground-engaging main sole portion. Traction studs 14 are evenly distributed over the sole portions 11 and 12 and have a shape as in the above-noted Patents and, therefore, can yield and deform in anydirection. The purpose of these traction studs 14 on the up3tanding lateral ed8e portion has been defined in the preceding ob~ec~s oE the present ivnention and will be Eurther explained wlth reference toFigure fi, 7, and 8.
The anti-~kidding foot-wear in the embodlment shown in Figllre 4 comprises a slightly difierent form of outsole, indicated by 15.
The ~ole 15 merely forms a cushion or soft pad on which 18 adhered the upper oi the foot-wear.
The outsole 15 includes an ice-engaigng main sole portion 16, an upstanding lateral edge portion 17, traction studs 14 and cavities 13.
The anti-skidding foot-wear in the embodiment shown in Figure 5 comprises another form of outsole 18. The latter is made of the :.
7 ~
same type of resiliently-collapsible materlal as the outsoles lO
and 15. The outsole 18 comprise~ an ice-engaging main ~ole portion 19 and an upstanding lateral edge portion 20. Cup-shaped cavities 21 are also formad in the 801e portion 19 and have their larger end downwardly opeil tc lncrease the softness of the sole, and to thus produce enhanced adherence upon collapsed engagement on ice. Traction studs 14 are provided on the main portion 19 and edge portion 20.
Obviously, it is po~sible to do away with the cavities 21 of Figure 5 or wlth the cavities 13 of Figure 1 to 4, if the sole i8 made of a sufficiently ~oft and collapsible material. Good adherence i9 achieved due to the presence of the lateral stud~ 14.
Figures 6, 7, and 8 illustrate three different collapsing behsviors of ~he collapsible outsole which result with p72dominant engagement of the lateral edge portion wlth the ice, compared to _he main sole portlon, Due to the traction studs added on the lateral edge portion, in ~uch cases adequate adherence of the outsole i8 maintained. l~us, for certain movements of the foot, such as when starting, stopping, jumping, changes of directions and lateral stop-ping, althougn th~ lateral edge portion is collapsed into engag~ment with the ice, the ~ddition of traction studs on ~he lateral edg,e portion compensates for the anti-skidding that would otherwi~e be lost, since leg8 of themain sole portion provides anti-~kLdding.
