Abstract
A shoe heel and sole structure composed mainly of two substrates or layers. The first substrate or layer is permanently attached to the shoe heel or sole, and the second substrate or layer comprises a wear layer that can be attached firmly to the first layer and removed easily for replacement. The first layer is in turn composed of two sublayers and has a number of small pocket-like cavities with openings for receiving the flat heads of pins or arbitrarily shaped protrusions, which are attached to the wear layer, i.e., the second layer. Furthermore, the first layer has a large central opening for receiving an attachment member of the wear layer. The combination of flat-headed pins and the attachment member of the wear layer are arranged such that they lock the wear layer securely to the first layer. Removal of the wear layer is achieved by folding back the attachment member out of the first layer and sliding the wear layer to disengage the flat-headed pins from the small pockets inside the first layer.
