Athletic shoe system and removable cleat

摘要

An athletic shoe system is provided comprising a shoe with shoe sole, non-metal screw boss, and cleat. The cleat of the preferred embodiment is usable with the shoe system of the present invention or with prior art athletic shoe systems. The preferred invention includes a removable plastic cleat having a disc-shaped body with a downwardly projecting generally circular pattern of ridges on its bottom side and an upwardly projecting threaded stem on its top side. A non-metal screw boss for embedding in the sole of a shoe has a cylindrical body with a threaded bore. An array of lobes project radially outwardly from the lower end of the cylindrical body and a corresponding set of truncated cone-shaped tabs project upwardly from the lobes. In use, a plurality of the screw bosses are embedded within the shoe sole during molding with the threaded bores of the bosses exposed through the bottom of the sole. The cleats can then be removably installed on the sole by threading their threaded stems into the threaded bores of the embedded bosses.
