Foot Orthoses:
- Custom-made inserts, shoe devices to assure proper position/comfort.
- A foot orthosis is used to align and support the foot; to prevent, correct, or accommodate foot deformities; and to improve overall function of the foot.
- During
walking, the normal foot changes from a supple, shock-absorbing structure to a rigid
lever for push off.
- A flat foot that is supple and does not invert and become rigid
does not effectively form a rigid lever for push off.
- Just the opposite occurs with a
cavus, or high-arched, foot. A cavus foot is rigid and lacks shock absorption. During
walking, the high-arched foot remains locked and fails to become supple for a
comfortable stance.
