Abstract
A multi-layered orthopedic insole has at least four layers. The first layer is leather, the second layer is molded high-density recycled latex foam, the third layer is a molded, rigid density cork-EVA (Ethylene-Vinyl Acetate) footbed, and the fourth or bottom layer is moleskin or moleskin coated to provide a natural grip for gripping a shoe insole. The different layers are fused to form the orthopedic insole of the present invention. The third layer of the multi-layered insole is generally thicker than the other layers and includes sidewalls covered in a leather wrap. The multi-layered orthopedic insole is specifically designed to provide comfort and support to a user's foot using the specified materials, shapes, and contours.
