Abstract
Athletic shoes with removable outsoles are disclosed. Each upper is designed to fit an individual foot and ankle of a particular wearer and such upper is provided with an insole securely and permanently connected therewith. Each insole terminates along its peripheral margin with one part of a bead-and-recess mechanically detachable locking member. A removable outsole is provided with a surface contacting tread which is selected to not only best match the surface of a particular sports area but also the condition of such surface at a particular time of use. A flexible member is permanently connected with the outsole and terminates along its peripheral margin with the other part of the mechanical locking member. The outsole and the insole are further connected together by mating Velcro members, tongues and grooves carried by the outsole and insole in paired relations, and other interlocking means.
