ABSTRACT:
A process for creating a foot support, and the support created thereby. The foot support transfers the force of walking uniformly over the surface of the foot from the points of metatarsal contact through the arch to the heel. A mold prepared to match the foot in relaxed configuration is used to cast a positive impression representing the relaxed surface of the bottom of the foot. The positive impression is leveled horizontally by a level across the high points, or contact points on the bottom of the foot. A casting is made, matching this horizontal level; when cured the casting forms the insert of the invention.
