The PowerStep is a shoe insert designed for use by individuals with lower extremity disabilities. This foot support system is intended to help relieve heel and arch pain, while preventing foot strain and injury. A full-length, prescription-like flexible polypropylene arch support is embedded in a double-layer polyethylene cushion casing. This controls feet rolling inward. A Sanitiz fabric cover reduces slippage and heat, helping keep feet drier. SIZES: Based on men's and women's shoe sizes.
