The custom IDEO was constructed and fit by the same prosthetist/orthotist for all limb salvage patients. The IDEO consists of a carbon fiber distal supramalleolar footplate, a proximal ground reaction cuff, and a removable, connective, posterior-mounted strut. A foam heel wedge of varying heights was often placed beneath the heel at the recommendation of the prosthetist/orthotist. The height of the wedge was consistent across testing conditions.
