An orthotic or propulsion plate defining a toe platform region, a longitudinal arch pad region, and a heel region. In the absence of an applied force to the top surface of the orthotic or propulsion plate and with the sole of the shoe resting on a horizontal surface, the orthotic or propulsion plate bows upward in the longitudinal arch pad region relative to the toe platform region and the heel region. In response to a force being applied to the top surface of the orthotic or propulsion plate, the bowed longitudinal arch pad region flexes downward relative to the toe pad region and the heel region to load a first preload force in the orthotic or propulsion plate. In response to the heel region thereafter moving upward, the bowed longitudinal arch pad flexes upward and the first pre-load force is released to deliver a propulsive force to the top surface of the orthotic or propulsion plate. |
