Abstract: A golf shoe spike fabricated from a soft thermoplastic rubber and including a one-piece body member with a planar base having a proximal surface and a distal surface, and a self-threading stud of a length shorter than the threaded spike socket into which it is inserted at installation. The spike includes an outer planar face which may further included a plurality of traction segments integral with the distal surface of the planar base and extending radially outward from the center of the planar base, each of said segments separated from adjoining segments by a notch. The spike cups when tightly screwed into a threaded spike socket, thus forming a rim on the outer circumference of the outer planar face.
