A shoe having a sole, an upper affixed to the sole and extending upwardly therefrom, a tongue fixedly and nonreleasably secured to the upper, an air pump affixed to the toe portion of the upper, a bladder in valved communication with an exhaust of the air pump and affixed to a surface of the tongue, and a deflator affixed to a heel portion of the upper. The deflator is connected in valved relationship to the bladder. A tubing extends along a surface of the upper from the bladder to the deflator. The bladder is inflatable by an action of the air pump. The deflator includes a valve having a pin extending upwardly therefrom and a flexible flap overlying the top of the pin. A downward pressure on the flexible flap will cause air pressure within the bladder to be released.
