An orthotic is a device that provides correction, support or protection to a part of the body. Foot orthotics can be classified by the material they are made from and can be divided into Functional Foot Orthotics and Accommodative Foot Orthotics.
Functional Foot Orthotics control joint movement by heel posting or wedges placed on the bottom surface of the orthotic shell. Helps reinstate normal gait patterns by deviating ground reactive forces through altered and ideally neutral positions of joints.
Accommodative Foot Orthotics do not attempt to reinstate normal gait patterns, instead they address foot symptoms by decreasing areas of peak pressure and reducing dynamic friction on the foot surface.
