Below is an image and some description of the components that make up an orthotic. Your orthotics may not have all of the components listed below, but these are the most commonly used components to make up a custom foot orthotic.
- Shell - provides the custom correction prescribed specifically for you. Made from a rigid, semi-rigid or flexible material.
- Extrinsic Rear Foot Post - a piece of firm material that provides stability to the rear of the orthotic and holds your rearfoot as prescribed.
