A device called a step-through ambulation aid which targets deficits encountered due to lower extremity paresis involving poor hip flexion. The device is comprised of a slidable plate that surrounds an inner liner. The plate surrounds a patients foot and has a means to removably secure the device to the patients foot. The use of the Step-Through Ambulation aid device on the bottom of a shoe allows reduction in friction forces encountered across most surfaces, including carpet, tile, wood, asphalt, and cement. The thin, smooth surface of the aid allows the foot to glide forward with virtually no resistance or friction from the walking surface. As a result, ambulation without additional physical assistance for leg advancement is made possible.
