The ideal insole for complete foot support, comfort, correct posture and mechanics. Dr Foot's insole is a unique foot support system intended to help relieve tendon pain, while preventing foot strain and injury. A full-length, prescription like arch support prevents and treats foot pain. The result: control for feet rolling inward (over-pronation), which can pull the entire lower body out of alignment. Dr Foot's Sport Insoles provide extra longitudinal support and cushioning for runners, plus lateral support for tennis, football and aerobics. Forefoot extensions prevent movement of the insert, which is important during sporting activities. A special fabric cover reduces slippage and heat, helping keep feet drier.
