Abstract
A combination and methods of making and using the combination are disclosed. Preferably the combination includes at least: an ankle and foot covering; a detachable sole detachably attached to the ankle and foot covering; and a detachable sole storage rack attached to the ankle and foot covering for use in storing the detachable sole when detached from the ankle and foot covering. The detachable sole preferably includes at least: heel and toe chassis portions each formed from a baffled support matrix and overmolded with tread portions; and an over-center latch coupled to an attachment hoop. The over-center latch preferably incorporates adjustment features to accommodate varying sizes of the ankle and foot coverings. Upon latching of a properly adjusted over-center latch adjacent the ankle and foot covering, a holding force transmitted through the attachment hoop secures the detachable sole adjacent the ankle and foot covering.
