The Back on Track Socks is a greatly appreciated product by our customers. Many people have problems with their feet, either caused by inflammation or poor circulation which leads to freezing. The socks work particularly well in combination with the Back on Track Insoles. If your heel is part of your particular problem, then the sock is the best choice because it covers the whole foot area. If you have sprained your ankle then the ankle brace may be a better choice as it provides a certain degree of support.
