ABSTRACT:
The invention pertains to an improved insole that combines insulating and therapeutic properties. The insole consists of a sandwich of several materials, namely a mesh that is adapted to rest on the bottom of some footwear, an aluminum foil whose shiny face is fixed with an adhesive onto the top face of the mesh. A polyethylene film laminated against the dull face of the aluminum foil also serves as the external face of an air bubble sandwich made out of one or two rows of air cells, separated from each other by a central polyethylene film, and covered by another polyethylene film. A second aluminum foil has its dull face laminated against a polyethylene film, and a mesh is then fixed on the shiny surface of the aluminum film with an adhesive. Finally, a resting strip for a foot is then fixed, by adhesive, to the top of the mesh.
