Abstract: A replaceable retention system for mounting golf spikes, cleats, and the like to the bottom of a shoe sole including a transverse plate and a holder. The holder is adapted to be insertable into a prepared cavity in the sole of the shoe and also includes an interior thread for receiving the threaded shank of a spike. The plate slidably engages structure in the holder which supports the plate in a transverse orientation to the interior thread of the holder whereby the threaded shank of the spike contacts and secures the plate in this arrangement. By this configuration, the plate may be inserted between the lower and upper layers of the sole for securely retaining the holder in position within the cavity in the lower layer of the sole. The removal and replacement of the plate, holders and spikes is thus facilitated by this invention.
