Abstract
An orthotic footwear system including a removable outsole, a removable reinforced hollow midsole attached to the top of the outsole, and a removable insole attached to the top of the midsole. A removable metatarsal pad can be attached to the top of the insole, and removable support inserts can be attached around the insole for additional support of problematic areas. Support inserts can be used to support the arch area, the heel area, or both. Each of the removable parts can be interchanged with parts of the same type having different ergonomic characteristics. The user can change the parts of the orthotic to suit their needs. Further, the support inserts can be used apart from the rest of the system, with any insole configured to receive them.
