Abstract: An orthotic insole has an outline resembling that of a foot. The portions of the insole corresponding to the calcaneus, first metatarsal head, fifth metatarsal head and toes consist of elastically deformable material having a relatively low first hardness. The portion of the insole corresponding to the lateral longitudinal arch consists of elastically deformable material having a second hardness greater than the first hardness. Alternatively, such portion is provided with a cavity at the underside thereof. The portion of the insole corresponding to the medial longitudinal arch is formed with a recess which receives an elastically deformable, interchangeable, wedge-like supporting member. The portion of the insole which corresponds to the area extending back from the metatarsal arch between the lateral and medial longitudinal arches consists of elastically deformable material having a third hardness greater than the first and second hardnesses.

Abstract: The invention relates to a device for elevating the forefoot in cases of peroneal nerve dysfunction, comprising four main elements: (a) a sock firmly fitting the foot; (b) a special dorsal plate member of a flexible and elastically yielding material which is anatomically fitted to the dorsum of the foot and extends between the forefoot and the lower tibial zone, which plate member is fastened to the dorsal surface of the sock; (c) elastic connector means engaging the opposite ends of the plate adjacent the forefoot and tibial zone ends; and (d) means for restraining the elastic connector in close proximity to the plate. The device has the advantages of simplicity of construction, ability to adjust the angle of repose of the foot by tension adjustment of the elastic connector and to compensate for footwear weight. Further, it can be worn with or without normal shoes, is inconspicuous, is easy to put on and take off, is comfortable and provides lateral stability to the foot.
