ABSTRACT:
A removably attachable traction gear for the underside of footwear having two primary components: a retaining member and a receptacle. These two components respectively replace the common screw and threaded receptacle systems found in for affixing traction gear to the underside of shoes. A partial turn of the traction gear securely locks the gear into the receptacle. The retaining member has a three-extension design so as to make the traction gear resistant to lateral forces applied to the ground-engaging end of the cleat. Locking is achieved through use of cantilevered fingers which press in during installation of the retaining member, and which spring back out to lock with mated indentations in the extensions. During installation a dome containing insole material is compressed. Unlocking is achieved through reverse turning the retaining member to force the springs back in, and removal is aided through re-expansion of the dome. In a preferred form, the invention is utilized to attach athletic cleats to a sport shoe.
