ABSTRACT:
A main body portion of a shoe includes a base having a heel and a sole, and an upper on the base. A lower sole is positioned below the base sole and is movable front to rear and back relative to the base sole. A transducer is provided in the seal and is connected to the lower sole. The transducer pushes the lower sole forwardly in response to heel pressure being imposed by the heel of the wearer on the heel of the shoe. After a forward shoe is set down on the ground, with its heel up and its lower sole contacting the ground, the main body portion of the shoe, with the wearer's foot inside of it, slides forward and adds length to the step.
