Orthopedic shoe appliance

1. An orthopedic shoe appliance, comprising:

a pad for providing support for midfoot arches, the second metatarsal, and the third metatarsal of a foot,

wherein the pad is configured to not provide support under a heel of the foot,

wherein the pad comprises a first portion configured to provide support to the midfoot arches, and a second portion that extends distally from a region corresponding to proximal ends of the second and third metatarsals to form an elongate extension that supports the second and third metatarsals and such that the distal end of the pad is configured to not reach a middle of the first metatarsal, the fourth metatarsal, and the fifth metatarsal,

wherein the first portion comprises a medial raised contour configured to be disposed under a medial arch and a lateral raised contour configured to be disposed under a lateral portion of the foot and the cuboid, and

wherein a width of the second portion is smaller than a width of the first portion, the distal end is narrower than a proximal end of the orthopedic shoe appliance, and the second portion, moving away from the distal end, widens generally continuously to reach the lateral raised contour.

2. The orthopedic shoe appliance of claim 1 , wherein the pad is attached to an insole, a midsole, an outsole, or a sock.

3. The orthopedic shoe appliance of claim 2 , wherein the pad is integrally formed with the insole, the midsole, the outsole, or the sock as a unitary piece.

4. The orthopedic shoe appliance of claim 1 , wherein the pad is attached to a footwear.

5. The orthopedic shoe appliance of claim 4 , wherein the pad is integrally formed with the footwear as a unitary piece.

6. The orthopedic shoe appliance of claim 1 , wherein different areas of the pad have different heights and/or durometers.

7. A method for improving foot stability, comprising:

providing the orthopedic appliance according to claim 1 ; and

disposing the orthopedic appliance on an insole, midsole, outsole, sock, or footwear.

8. The orthopedic shoe appliance of claim 1 , wherein the pad is configured to apply an upward force on proximal ends of the second metatarsal and the third metatarsal and on the lateral longitudinal arch and medial longitudinal arch of the midfoot arches, which cantilevers the first metatarsal, the fourth metatarsal, and the fifth metatarsal in a downward direction.

9. The orthopedic shoe appliance of claim 1 , wherein the pad is configured to extend to metatarsal necks, proximate to metatarsal heads, of the second and third metatarsals.

10. A method for manufacturing an orthopedic appliance, comprising:

obtaining a pad;

shaping the pad to have a first portion to provide support for midfoot arches, and a second elongate extension portion to provide support for the second metatarsal, and the third metatarsal of a foot, the elongate extension extending from a region corresponding to proximal ends of the second and third metatarsals to support the second and third metatarsals, but to not provide substantial support under a heel of the foot or under proximal ends of any of the first metatarsal, the fourth metatarsal, and the fifth metatarsal;

shaping the pad such that the first portion comprises a medial raised contour configured to be disposed under a medial arch and a lateral raised contour configured to be disposed under a lateral portion of the foot and the cuboid; and

shaping the pad such that a width of the second elongate extension is less than a width of the first portion, the distal end is narrower than a proximal end of the orthopedic shoe appliance, and the second portion, moving away from the distal end, widens generally continuously to reach the lateral raised contour.
