Abstract: A shoe spike apparatus permitting quick interchange or replacement of gripping elements, which includes a shoe sole attachment plate with a downwardly depending stabilizer shaft, a plurality of spring fingers affixed to the plate, and a spike member having a base provided with a recess for receiving the stabilizer shaft and an exterior geometric configuration on the base which mates with the spring fingers so as to retain the spike member firmly and without lateral movement to the attachment plate and shaft. In one embodiment a circular construction of engaging surfaces of the spike member and the socket and spring fingers allows rotational movement of the spike member relative to the socket to prevent rotational stress which might otherwise tear the sole attachment plate from the sole in which it is embedded. Rigid contact surfaces permit only unidirectional removal of the spike member from the socket for ensuring the integrity of the snap lock mechanism.

Abstract: Shoe spike apparatus permitting quick interchange or replacement of gripping elements, the apparatus including a shoe sole attachment plate with a downwardly depending stabilizer shaft; a snap ring socket affixed to the plate; a snap ring received within the socket; and a spike member provided with a recess for receiving the stabilizer shaft and a groove for receiving the snap ring to hold the spike member firmly and without lateral movement to the attachment plate and shaft. Circular construction of engaging surfaces of the spike member and the socket and snap ring allow rotational movement of the spike member relative to the socket to prevent rotational stress which might otherwise tear the sole attachment plate from the sole in which it is embedded. Rigid contact surfaces permit only uni-directional removal of the spike member from the socket for assuring the integrity of the snap lock mechanism.
