About Orthopedic Shoes:
Orthopedic Shoes are shoes designed for people with problem-prone feet. Orthopedic shoes should have a firm heel, a heel that is not too high, a wide toe box, and a rigid shank (inner construction material) for stability. Orthopedic Shoes may also be referred to as Pedorthic Shoes.
