  • Patent number: 4803989
    Abstract: Metatarsal pad structured with relation to the foot for which it is intended so that it bridges across the width of the five metatarsal bones; a configuration at the front is such that each metatarsal is supported just posteriorly of the head thereof and with a height to raise the heads of the metatarsals from weight bearing and transfer of the weight over a larger area. The front of the pad is characterized by a radius of curvature of about 3/16 of an inch in the vertical plane and the frontal outline in the horizontal plane is preferably convex in the central portion while being slightly concave on either side thereof; this conforms to the shape of volar surface of the metatarsal as it develops the head of each metatarsal. The alternate concave and convex frontal outlines follow a line just posterior to the head of the first metatarsal and progressing laterally just behind the head of each subsequent metatarsal. The pads are asymmetric and are provided for the left and the right foot.
