SHOE WITH QUICK TIGHTENING UPPER

摘要

A shoe (90) having at least one elongated shape memory alloy element (120A, B and C) and an electric circuit which, when energized, will produce a tightening of the shoe upper (40) around the foot of a wearer. In a preferred embodiment, the shoe (90) in one of a pair of golf shoes and the circuit (Figure 5) 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 (90) provides a power source to produce a current in the circuit (Figure 5) that heats the shape memory alloy (120A, B and C) causing it to reduce its length providing the tightening of the shoe uppers (40).
