Abstract
Abstract This invention pertains to the encapsulation of a cellular insert, formed of various woven cellular components, or fabricated to a grooved design formed of a series of linearly woven strands, each of which presents various voids or cavities within their formed structure, and then foamed in place within a polymer formed sock liner or insole for use within footwear, and particularly an athletic shoe, including the sole of a walking or other shoe. The cellular insert may be formed of a series of woven or wound cellular shaped components, having their voids therein, and which may be arranged intermediate a pair of liners, which form the upper and lower liners for the formed insert, or arranged upon a singular liner, or having the liner woven through its midpoint, in order to provide for its rather proper location within the structure of the polymer formed sole or insole. In addition, the cellular insert, as previously explained, may be formed of a series of longitudinally and crosswise interwoven strands of linear material, which form various symetrically shaped channels or grooves, this cellular insert also being embedded within a foam formed sock liner, for use internally within an athletic or other shoe for comforting the wearer of the shoe and its incorporated liner as in usage during participation within a variety of sporting events, such as football, basketball, jogging, court playing, or even walking, or other such endeavors.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
262 words
A cushioning and impact absorptive 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 said sole, means operatively associated with the shoe sole to provide cushioning for the said footwear during its application, said means also being formed of a polymer-like material, a cellular insert, said cellular insert being applied within the polymer-like material formed associated with the said shoe sole, said cellular insert comprising upper and lower layers of woven polymer material, and also comprising a series of sinusoidally shaped cellular components formed of woven polymer-like material and arranged intermediate and connecting to said layers of said polymer material, said cellular components formed having upper, lower, and side surfaces, said layers of polymer material connecting with the upper and lower surfaces of the said cellular components, said cellular components having cavities generally formed therethrough, with said formed cavities being arranged intermediate the said upper and lower layers of the cellular insert, the series of cellular components provided therein being secured together along their contiguous side surfaces, said cellular insert being arranged substantially aligned within the said footwear means during shoe usage, said cellular insert as formed of woven polymer material having a hardness greater than the polymer-like material forming the said shoe sole, whereby the cellular insert formed within the sole tending to effect the absorption of any forces of impact, while furnishing conservation of energy for the user of the footwear during application.
Claim 2
Dependent Claim
