Specifically designed to treat plantar fasciitis, Achilles tendonitis and heel pain. Using two interconnected air cells located under the foot arch and in back of the heel, the AirHeel applies pulsating compression with every step to help reduce swelling, discomfort, and to enhance circulation. Made of lightweight Neoprene fabric and simple to apply – just slip it on like a sock and adjust the fit with one strap. Latex free.
