Arthritis & Diabetes Insole

摘要

An insole advantageous for arthritic or diabetic patients comprises three layers and provides an arch support and an integral heel receiving area. The insole has a generally foot-shaped bottom layer having a length extending from a heel area to a toe area, a top surface and a bottom surface. The bottom layer's bottom surface preferably comprises one to three indentations formed integrally therein and is preferably made of an EVA foam. Insert layers are secured to each of said indentations. A middle layer having a first and second side is secured to the bottom layer's top surface adjacent the middle layer's second side and is preferably made of a synthetic rubber layer. The middle layer takes the shape of the bottom layer. A top layer is coextensive with and secured to the middle layer's first side. The top layer composition is selected according to the intended use.
