ABSTRACT:
An attractive, sleek, comfortable, light weight ladies shoe includes a hard molded, polyurethane unitary body forming an elevated heel, a shank and an outer sole. The body has a load bearing upwardly directed face and a flange extending upwardly approximately at right angles to the face from the periphery of the outer sole and shank to the exclusion of the heel. A resilient foam polyurethane soft cushion layer having a thickness of approximately one-quarter inch and an upper face as well as a bottom face bears against the load bearing face of the body. A sheet of material covers the upper face of the cushion layer and is secured to the upper face of the body underneath of the cushion. An upper is secured in place between the upwardly directed face of the body and the bottom face of the cushion layer. The flange extends above a load bearing face of the sole by approximately three-eighths of an inch so an upper surface of the sheet material is approximately coplanar with but slightly above an upper edge of the flange. The cushion layer, sheet of material and upper are held and captured in place by the flange and embedded in the body. The heel includes an interior longitudinally extending steel support post and the shank includes an interior longitudinally extending steel support plate embedded wholly within the shank.
