HTP Heel Seat Wraps provide plantar fascia support for relief of heel pain even without shoes. It's great to wear with sandals, too. Whether you suffer from plantar fasciitis, heel spurs, arch pain or calcaneal bursitis, HTP Heel Seat Wraps offer you a way to relieve heel pain. A patented plantar fasciitis bar at the midfoot applies upward pressure and compression to the plantar fascia, preventing it from overstretching, tightening, and consequently causing heel pain. The cupped design redistributes your heel's natural fat pad to provide a soothing cushion beneath the heel bone. Made from 100% neoprene.
