ABSTRACT:
An athletic shoe has a sole that is slightly, if at all, thicker than soles that are common to athletic shoes. A plurality of spikes or cleats are caused to depend from the bottom of the sole by an actuation mechanism that has a rotatable knob projecting from the back of the athletic shoe. The structure of the sole provides for openings to the undersurface to allow spikes to pivot outwardly beyond the undersurface of the sole. The actuating device has an actuator slide that translates a transverse movement to a pivotal movement of the spikes.
