Orthopedic insoles

Abstract

The present invention generally relates to orthopedic insoles, either aftermarket insoles that can be added onto or exchanged for the insoles an existing shoe was manufactured with, or insoles that a shoe is built around on during manufacture. Specifically, embodiments of the present invention relate to orthopedic insoles that comprise an angled forefoot area for varus correction. In particular, in embodiments of the present invention, the inside area of the inner right forefoot is raised to create an angle to accommodate forefoot varus. Also, in embodiments of the invention, the insoles may comprise a plantar fascial groove configured longitudinally on the arch of the innersole, for accommodation of tight fascia. Further, the heel area of the innersole may be elevated to accommodate for equinus foot. Insoles of the present invention provide both static and dynamic support.
