Abstract: A replacement cleat or spike structure for attachment to the outer surface of a worn cleat or spike depending from the sole of a shoe, having a generally hollow, conical spike member attached at its base to a circular, dish-shaped flange. The hollow portion of the spike member is of a sufficient dimension to receive the nub of a worn spike attached to the sole of a golf shoe. The spike structure is placed onto the nub and flange of the worn spike and is held in place by epoxy or other suitable adhesive means.
