What are full arch contact orthotics, and how are they different from other orthotics?

Full arch contact orthotics maintain contact with the longitudinal arch of you foot at all times, providing support during all phases of walking, running and other weight bearing activities. Other orthotics often support the foot when it is neutral, but fail to maintain arch support when the foot starts moving, sometimes allowing too much motion (pronation or supination). This can often result in pain and injury.
