ABSTRACT:
An athletic shoe including a shoe upper and an outsole connected to the shoe upper is provided. The outsole defines a plurality of spike receiving openings therein. A plate is located between the shoe upper and the outsole, and includes a plurality of spikes attached thereto. The plate is movable within the upper between a spike-exposing position whereby the plurality of spikes extend outwardly through respective openings formed in the outsole, and a spike-retracting position. An inflatable bladder is located between the plate and the outsole. When inflated with a fluid, the bladder lifts the plate upwardly into the spike-retracting position, and holds the plate in the spike-retracting position during shoe wear. An exhaust communicates with the bladder for exhausting the fluid contained in the bladder. When the fluid is exhausted, the plate is movable into the spike-exposing position by the weight of the wearer during shoe wear.
