ULTRA HEEL: Ultra Heel is made of two types of gel: Soft-X gel cushions against impact to the heel when active. Soft-X20 gel in the center relieves the heel point and heel spur when pain and inflammation is present. Our strong heel bones bear most of our weight. However, the heel area is subject to overuse injuries, and strains to ligaments and muscles in and around the foot and ankle. The Achilles tendon and the plantar fascia ligament both connect to the heel. When the tissue located around the heel becomes inflamed it can be truly debilitating. While you seek medical treatment, and the healing effects of rest and time to reduce swelling and inflammation, Ultra Heel can help. Ultra Heel's shock absorbing, soft gel heel cup which cushions against weight and impact. In addition, Ultra heel is cupped to help prevent injury from abrupt twisting. Ultra Heel also protects the foot, knee, and hip joints, as well as the lumbar and cervical spine from impact and other overuse injuries. Rinse by hand in clean water, pat dry.
