ABSTRACT:
A process is provided for making a cleat. The cleat includes a spike member, having a tip and a base, the base being wider than the tip. The cleat also includes a washer member, having a perimeter portion and an inner portion, the perimeter and inner portions lying in separate planes. The inner portion has an aperture. The spike member is inserted through the aperture, so that spike member projects out from the lower face of the inner portion. Then material is molded around the washer member's perimeter portion, the upper face of the inner portion, and the base of the spike member, so as to hold the spike member in fixed relation to the washer member. In a preferred embodiment of the process, a barrier is placed around the lower face of the washer member's inner portion during molding, so as to prevent the material from coming into contact with the lower face of the washer member's inner portion and that portion of the spike member extending from the lower face. Preferably, the spike member is made from a wear-resistant material, such as steel, hard metal alloys, ceramic, ceramic-metal compounds, tungsten carbide or titanium carbide. The material molded around the washer member is preferably a thermoplastic. The completed cleat assembly can be molded into the sole of a shoe so that the spike member projects from the sole.
