Abstract
A removable orthotic shoe sole insert for a patient having a high arch comprises a built-up heel portion with a deep cup shape with a flaring around the heel pad area for containing the fatty fibrous heel pad, a arch area formed lower than the arch of the wearer and a forefoot portion just lateral to the first metatarsal head and lateral sesamoid of the foot and extending to the lateral edge of the insert. A shallow divot or depression is formed for receiving the first metatarsal and its underlying hallux sesamoids. The shoe sole insert is designed to accommodate the majority of foot sizes and is sized by the length from the posterior heel to the first metatarsal head of the foot so that the first metatarsal head is positioned in the shallow divot of the insert.
