Insoles that improve gait overpronation

Abstract

An insole for improving excessive pronation in gait includes an insole body, a wedge-shaped forefoot pad, an arch support pad, and a heel pad. The insole body is a cushioning pad that provides pressure relief and rebound to the foot. The wedge-shaped forefoot pad is located on the insole body relative to the forefoot position. The arch support pad is located on the insole body relative to the midfoot position. The heel pad is located on the insole body relative to the heel position. The wedge-shaped forefoot pad is a modular patch with decreasing thickness from the medial side of the forefoot relative to the first metatarsal bone to the lateral side of the forefoot relative to the fifth metatarsal bone. This creates a braking-like function, inhibiting the tendency of excessive arch collapse and preventing the center of gravity from rolling excessively to the medial side of the forefoot, thus maintaining it stably in an ideal midline position.

Claims

1. An insole for improving excessive pronation in gait, comprising an insole body, a wedge-shaped forefoot pad, an arch pad, and a heel pad, wherein the insole body is a cushioning pad that provides pressure relief and rebound to the foot; the wedge-shaped forefoot pad is disposed at the position of the insole body relative to the forefoot; the arch pad is disposed at the position of the insole body relative to the midfoot; and the heel pad is disposed at the position of the insole body relative to the heel; characterized in that the wedge-shaped forefoot pad is a modular patch with decreasing thickness from the medial side of the forefoot relative to the position of the first metatarsal bone to the lateral side of the forefoot relative to the position of the fifth metatarsal bone.

2. The insole for improving gait overpronation as described in claim 1, wherein the thickness difference of the wedge-shaped forefoot pad is between 2mm and 6mm.
