Abstract: To make a foot orthotic device shaped to correct the plantar surface of a patient's foot from an appropriately shaped body, that body is made by taking measurements of various characteristics of the patient's foot directly from that foot, including measurements of various aspects of the patient's arch, generating a model of the plantar surface of the foot from these measurements, then modifying this model in accordance with a practitioner's corrective prescription, and using those modified measurements to control a shaping device such as a milling machine to produce on said body a three-dimensional surface constituting the desired corrected shape for the patient's plantar surface.

Abstract: An orthotic device for insertion into a high-heeled shoe is provided. An orthotic device made in accordance with the instant invention virtually eliminates the problems associated with the wearing of high-heeled shoes, particularly pronation effects, general foot discomfort, posture problems, toe pain, and arch pain. The orthotic device comprises a right or semi-rigid shell for positioning beneath the heel of the foot and extending forwardly towards the toes of the foot. The shell terminates behind the five metatarsal heads of the foot, and is shaped whereby to permit the first metatarsal head freely to evert and plantarflex under load, and is shaped such that the heel of the foot is carried substantially parallel to or slightly backwardly inclined relative to the ground plane.

Abstract: A foot orthosis for correctably realigning and repositioning specific anatomic segments of the human foot consists of three functional components, namely, a heel complex segment and two longitudinal forefoot segments--namely, a medial segment and a lateral segment.The heel complex segment is independently connected to each longitudinal forefoot segment by a connector. The segments function sufficiently independently from one another to consider the device a triplanar foot orthosis.
