ABSTRACT:
An athletic shoe has a shoe portion with a sole having a number of projections extending from the sole. A detachable sole with a number of cleats or the like extending therefrom has grooves designed to mate with the projections on the sole of the shoe. Each of the projections and grooves have tapered edges such that the detachable sole will only be released from the sole of the shoe when a specified force is applied across the width of the shoe. In addition, the projections may have notches along their edges which mate with projections extending into the grooves on the detachable sole to facilitate the holding of the detachable sole on the sole of the shoe.
