Abstract

The invention relates to an apparatus and methods for incorporating a medial/lateral counter foot stabilizer into shoes. In an embodiment, the medial/lateral counter foot stabilizer of the invention comprises a plantar aspect which extends the length of the sole of a foot, side walls, a metatarsal arch support, a lateral arch support, a medial arch support, and a heel cup counter. The stabilizer of the invention mimics a preferred foot shape, provides support for the metatarsal, medial, and lateral arches, and restricts pronation and supination of the foot. The stabilizer of the invention is designed to be integrated into commercial shoes during the manufacturing process as a method of providing foot support which is currently unavailable in commercial shoes.
