Abstract: An adjustable orthotic insole and a unique method of implementation has a shell and a sole lifter that is to correct malalignment of lower extremities and other functions such as cushioning, massage, etc are not anticipated. The distribution of ground reaction force is changed due to the orthotic effect of the sole lifter. A user adjusts position and thickness of the sole lifter incessantly until malalignment of lower extremities is restored to optimal alignment symmetrically. The present invention employs a unique method that the sole lifter is always opposite to rear foot lifter. Once the malalignment of lower extremities is corrected by the orthotic insole, the user would be able to maintain good posture and ambulate in ideal gait. Therefore, symmetric and coordinated movements are harmonious with balanced muscle function. The musculoskeletal system would be protected from overuse injury.

Abstract: A foot orthosis includes a shell and a corrective wedge assembly. The corrective wedge assembly is attached to the shell via mechanical locking mechanism. Therefore, the placement of wedges on the shell can be versatile and adjustment is convenient.
