An ankle-foot orthosis for relief of a patient from orthopedic dysfunctions comprising, in combination, a shoe and a brace assembly. The brace assembly comprises a leg member and a pair of opposed upright members. The leg member is constructed and arranged such that portions of the inner surface of the leg member complementarily conform to portions of the rear and sides of a patient's lower leg. Each upright member of the pair of upright members is connected to the leg member and extends downwardly from the leg member to a distal end. The support brace further comprises means for resiliently connecting a portion of the support brace to the upper portion of the shoe. In use, at least a portion of the distal ends of the upright members is inserted into a portion of the heel portion of the shoe between sides of the shoe and the patient's foot.
