ABSTRACT:
A basic design of heel-needing shoe is provided having a sole member made of semi-rigid molded plastic material including a thickened heel stub or jack portion having a downwardly-tapering outer perimetrical sidewall extending about the back and the lateral sides, and a downwardly-opening cylindrically-walled centrally-located socket. The upper surface of the sole member overlying this thickened portion is preferably provided with a small-diameter opening axially communicating with the well. The upper end of the heel is provided with a centrally located axially upwardly projecting cylindrical boss, preferably centrally provided with an upwardly opening threaded bore. The boss is surrounded by a flat upper end surface. An upstanding flange extends about the back and sides of this end surface. The inner surface of this flange tapers to match the heel jack. The heel is disassembly assembled to the basic heel-needing shoe by inserting the heel boss into the jack socket and threading a screw through the sole opening into the boss bore. Two designs of shoe/heel visible interface are shown.
