A prescription foot orthotic is an in-shoe brace designed to correct abnormal foot and lower extremity function [the lower extremity includes the foot, ankle, leg, knee, thigh and hip].
Accommodative foot orthotics are used to cushion, pad or relieve pressure from a painful or injured area on the bottom of the foot. They may be designed to help control an abnormal function of the foot.
Painful callouses on the bottom of the foot, diabetic foot ulcerations, sore bones on the bottom of the foot and other types of foot pathology can also be relieved by accommodative orthotics.
Functional foot orthotics are used to correct abnormal foot function while also correcting abnormal lower extremity function. They are also useful in the treatment for a wide range of painful conditions of the foot and lower extremities.
