Abstract
A leg apparatus shoe sole has an upper sole member and a lower sole member interconnected by expanders so as to be movable towards and away from each other wherein the expanders are connected with a remote actuator by a drive wire. The actuator is operated to reduce the thickness of the shoe sole when the associated leg is the free leg and to increase its thickness when the associated leg is the supporting leg.
