A cleat or calk for use with boot soles and the like to provide enhanced gripping and wear life includes a generally cupshaped spike member defining a plurality of pointed spike elements spaced about and projecting from a base adapted for mounting on a boot sole through a mounting shank and sole-mounted cleat anchor. In one embodiment, spring means cooperates with the spike member and mounting shank to enable limited pivotal movement of the spike member when mounted on a boot sole so as to accommodate uneven surfaces engaged by the spike member, while effecting self-leveling of the spike member upon release from the underlying surface. |
