Abstract
Abstract Shoes incorporating a multiple chambered sole member inflated to a pressure above atmospheric, and disposed above and adjacent to an outsole having a deflectable web and projecting elements, such as ground-engaging studs, depending from the web and disposed in spaced geometric relation to each other to distribute loads imposed on the studs through a greater area of the inflated sole member to a wearer's foot, thereby enhancing its support and comfort.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
137 words
A structure adapted to form part of a shoe for receiving a person's foot, comprising a sealed sole member of elastomeric material providing a plurality of deformable intercommunicating chambers adapted to be inflated with a gaseous medium under pressure, an outer sole including a thin elastic deflectable web portion underlying and in load transmitting relation to said sole member and ground engaging studs spaced substantially from each other transversely of the outer sole and longitudinally of the outer sole and secured to and depending from said web portion, said web portion having a thickness of from about 0.015 inches to 0.080 inches, whereby said studs are shiftable with respect to each other and with respect to said deflectable web portion and sole member in transmitting loads between the person's foot and the ground engaged by said studs.
