Abstract
A golf shoe is proposed which has a sole that is provided with spikes. To permit the golf shoe to perform effectively as a walking shoe and as a striking shoe, each spike is inserted in and axially movable relative to the sole and on top of the sole comprises a pressure-applying plate which bears on the top of a resilient abutment.
Claims5
A golf shoe comprising
- (a) an outsole defining a plurality of through holes,
- (b) an resilient abutment disposed on top of the outsole and covering said through holes, the resilient abutment defining a like plurality of through holes in alignment with the through holes in the outsole,
- (c) a like plurality of spikes, each of which comprises
- (1) a pressure-applying plate bearing on said abutment from above and
- (2) a shank depending from said plate and extending through respective ones of said aligned through holes in the abutment and outsole, and
- (d) an insole disposed on top said abutment, the pressure-applying plates of the spikes being disposed between the abutment and the insole, and the plates conforming to adjacent portions of the insole whereby said spikes are movable between a generally retracted position, in which said spikes do not substantially protrude below said outsole when a golfer is walking in said shoe, and an extended position, in which localized pressure upon respective ones of the adjacent insole portions causes respective ones of the pressure-applying plates to depress the resilient abutment and to move respective ones of the spikes axially through the aligned through holes so that at least certain of said spikes project below said outsole when the golfer performs a swinging motion.
