An insert for a shoe or a shoe interior comprises a central portion which prevents excess pronation, a front portion which extends arcuately and transversely across the foot to support the transverse metatarsal arch, a rear portion which extends transversely across the foot and contacts the forward edge of the heel, a lateral, slanted edge which is aligned parallel to the longitudinal axis of the arch and support the fifth metatarsal shaft of the foot, and a fourth portion which slopes medially. The device is designed to fit the area of void on the plantar side of the human foot to support the structure of the foot to prevent excess pronation and to substantially reduce foot morbidity.
