Abstract
A shoe having at least one elongated shape memory alloy element and an electric circuit which when energized will produce a tightening of the shoe upper around the foot of a wearer. In a preferred embodiment, the shoe in one of a pair of golf shoes and the circuit in the shoe is energized by a switch in the heel that is turned on by the golfer clicking his heels together. Typically the golfer does this prior to each important swing of a golf club. A battery contained in the shoe provides a power source to produce a current in the circuit that heats the shape memory alloy causing it to reduce its length providing the tightening of the shoe uppers.
