    Abstract: A high heel shoe with a self seating removable heel portion includes a shoe body having a sole portion with a toe and a heel area, the heel area being elevated substantially above the toe area so that the shoe sole is inclined between the toe and the heel and at the heel area. The heel portion of the shoe sole has a socket with a forwardly facing open end and a closed rear end, the socket having a side wall forming a continuous dove-tail joint portion. The high heel has an enlarged upper end portion with an inclined upper surface and a dove-tail locking member extends upwardly from the high heel upper end portion inclined surface, the locking member including a pedestal with a dove-tail side wall that corresponds to and registers with the socket so that the heel can be attached to the socket by moving the heel pedestal into the socket into a fore to aft direction, and wherein the heel is constantly loaded rearwardly during use insuring a seating of the heel upon the socket during use.
