represent the next generation in correcting foot and body mechanics. Instead of restricting foot motion by hard or semi rigid orthotics shells and arch supports, Posture Control Insoles® are designed to cause the muscles in your feet and calves to facilitate proper correction of your foot mechanics. Gait and posture is corrected naturally. The muscles that control your feet and your body are strengthened by free natural motion. Posture Control Insoles correct both hyperpronation and supination. http://www.mortonsfoot.com
