Abstract
Athletic shoe sole having cleats with exchangeable gripping elements designed such that the threaded mounting studs for gripping elements are firmly anchored to the sole, and that the associated caps of the gripping elements can be detached therefrom without damage or destruction to the threaded studs. This is achieved in that each threaded stud (2) and the screw-on cap (5, 5a) is in the shape of a cone whose broad base faces the shoe sole (1). The thread is a single or multiple thread (4) having only partial turns of screw threads. Finally, run-on surfaces (12, 13) effective during screw-on of lock elements (10, 11) of the cap are less inclined relative to the plane of the sole (1) than the flank surfaces that act as locking surfaces (14, 15) which are also inclined.
