Footprint Insoles are the only real custom orthotics available without going to a doctor. Used by pros and customers swear by them. These insoles push what's possible for the human body and make careers last longer! If you have ankle, knee, hip and back problems, it's most likely all stemming from your arch. Think of your body as a machine. Your cartilage is like bushings. Too much weight is put on the arch, either from being overweight or constant and repetitive jumping/impact, next the achilles tendon/ankle goes crooked upon the impact which throws off the knee.
