Abstract:

A shoe has spikes that can be retracted merely by moving an external operating member. Replaceable lower sole members can be selected and attached to the shoe based on ground surface conditions. Also, a shoe package includes one shoe with spikes and one shoe with retractable spikes or without spikes. A method of swinging a golf club using the shoe package permits a golfer's rear foot to be firmly planted while allowing the golfer's front foot to rotate and glide thus facilitating proper follow through.
