Say Goodbye to Foot and Heel Pain with WonderZorb® Soft Silicone Orthotics-the #1 product recommended by medical professionals… Silicone is the secret! Studies have shown that high performance soft silicone cushions can relieve sore, aching heels, ankles-knees and back more effectively than custom orthotics costing hundreds of dollars. Made from a clear medical grade silicone for extra comfort, WonderZorb® Cushions absorb the foot shock forces that can aggravate pain and discomfort with every step. Contouring to cradle the foot, these technologically advanced cushions feature a softer silicone dot to provide maximum pain relief where it’s needed most. WonderCup® consists of two different densities of silicone for heel and back discomfort. Men’s Shoe Size 8-10 Women’s Shoe Size 10-11+
