ABSTRACT:
A shoe is provided having a soft, and compliant insole and a cushioned outsole. In manufacturing the shoe, the insole is temporarily stiffened by a relatively firm member to which it is bonded by means of a wax. This enables the insole to withstand the normal lasting procedure. The outsole is provided with a cavity for receiving a cushion therein. The shoe upper is attached to the outsole such that the insole overlies the cushion. Once the shoe is completed, the wax bond between the insole and its stiffener is heated to allow the separation and removal of the latter.
