Abstract
Abstract A spike assembly for a sports shoe comprising a spike body formed into a screw element at one end and a spike element at the other end. The middle portion is formed into a flange with a serrated surface facing the screw element. A washer having a serrated surface is mounted on the screw element so that the serrated surfaces of the washer and the flange may engage each other to prevent turning. An annular member made of synthetic resin is also mounted on the screw element to support the washer which is provided with peripheral projections adapted to be engaged with the sole of the shoe.
