Medical Professionals recommend the Steady Step Sol Step to provide plantar shock absorption for heel pain and reduced inflammation. An optional shock-absorbing gel heel pad provides 5 - 10 minutes of cold therapy, while light compression treats edema and swelling. Constructed of 1.5mm neoprene, Sol Step can be worn without modification in most shoes. Sol Step fits like a stocking and should feel comfortable; if toes or feet feel number or tingling, a larger size is needed.
