An orthopedic component in the form of a resilient subshell is connected to and extending flexibly outwardly from the frame assembly. The subshell has a main body and a perimeter edge portion secured along the periphery of the main body wherein the perimeter edge portion is formed from a material having less hardness than a material used to form the main body. The strap is connected to at least one end portion of the subshell.
