<p>An insole insert (1) comprises a unitary body member (7), constructed of material having a selected material compression resistance and having a bottom portion (37) with a toe portion (53), a heel portion (45), an arch portion (47), and a metatarsal support portion (55). The metatarsal support portion (55) extends rearwardly from the toe portion (53) alongside the arch portion (47) and forms a boundary (73) beginning beneath the juncture between the user's first and second metatarsal shafts (M1, M2), arcuately passing beneath the user's first through fourth metatarsal necks (N1, N2, N3, N4), and passing beneath the juncture between the fourth and fifth metatarsal shafts (M4, M5) and the juncture between the cuboid and the lateral cuneiform and navicular bones. A relief is generally formed along the boundary. Perforations (91) in the body member provide at least one perforation-modified portion (89), having a selected effective compression resistance with a magnitude less than the magnitude of the material compression resistance, and a non-perforation-modified portion (93) not having the perforations.</p> |
