Abstract
Abstract This invention pertains to the encapsulation of a cellular insert, in the form of cellular components, formed of woven material fabricating such cellular components that present voids or cavities therein, or which may be formed from spirally or helically wound strands of a polymer having a hardness exceeding that of the foamed or other polymer composition in which the insert locates, as within the structure of a sole for an athletic shoe. The cellular insert may be formed of a series of woven or wound cellular shaped components, having the voids therein, and which may be arranged intermediate a pair of liners, which also may be of woven material, in order to provide for its rather proper location within the structure of the polymer foamed shoe sole, be totally embedded therein, but yet very effectively function as a means for cushioning or absorbing the forces of impact exerted upon the shoe sole during application of the athletic shoes during participation within a variety of sporting events, such as football, basketball, jogging, court playing, or the like.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
215 words
A cushioning and impact absorption means for application within footwear of the type having a shoe upper affixed to a sole formed at least partially of a polymer like material, comprising, a shoe upper and a shoe sole, said upper secured to a cellular insert applied within the polymer like material, forming said sole, said cellular insert comprising layers of woven polymer material, and also comprising a series of cellular components formed of woven polymer material and arranged intermediate and connecting to said layers of material, siad cellular components having upper, lower and side surfaces, said layers of polymer material connecting to the upper and lower surfaces of said cellular components, said cellular components having cavities generally formed therethrough, with said formed cavities being arranged intermediate the said upper and lower surfaces of the cellular components, said series of cellular components provided therein being secured together by strands of linking means along their contiguous side surfaces, said cellular insert being arranged substantially aligned within the sole structure during shoe usage, said cellular inserts as being formed of a woven polymer material having a hardness greater than the polymer material forming said sole, whereby the cellular insert formed within the sole tending to effect absorption of any forces of impact encountered by the footwear during usage.
Claim 2
Dependent Claim
215 words
A cushioning and impact absorption means for application within footwear of the type having a shoe upper affixed to a sole formed at least partially of a polymer like material, comprising, a shoe upper and a shoe sole, said upper secured to a cellular insert applied within the polymer like material, forming said sole, said cellular insert comprising layers of woven polymer material, and also comprising a series of cellular components formed of woven polymer material and arranged intermediate and connecting to said layers of material, siad cellular components having upper, lower and side surfaces, said layers of polymer material connecting to the upper and lower surfaces of said cellular components, said cellular components having cavities generally formed therethrough, with said formed cavities being arranged intermediate the said upper and lower surfaces of the cellular components, said series of cellular components provided therein being secured together by strands of linking means along their contiguous side surfaces, said cellular insert being arranged substantially aligned within the sole structure during shoe usage, said cellular inserts as being formed of a woven polymer material having a hardness greater than the polymer material forming said sole, whereby the cellular insert formed within the sole tending to effect absorption of any forces of impact encountered by the footwear during usage.
