Rocker soles can be as beneficial to mechanical control of painful foot disorders as foot orthotic devices. While foot orthotic devices address problems of frontal plane and transverse plane motion, rocker soles address problems of sagital plane motion. Since walking occurs on the sagital plane, there are a number of problems well addressed by this modality when applied in cojunction with an understanding of biomechanics. Like orthotic devices, rocker soles inhibit unwanted c
