Abstract
A shoe includes a heel support for receiving a rotatable and replaceable rear sole to provide longer wear. The shoe may also include a graphite insert supported by the heel support between the heel and the rear sole to reduce midsole compression and provide additional spring. The replaceable rear sole and the graphite insert allow the shoe to be adapted to different desired performance characteristics depending upon the intended activity and terrain or playing surface.
