What is the other heel cushion for?
A. The AchilloTrain support has a heel cushion built in to take pressure off the Achilles tendon. Every AchilloTrain product comes with an extra heel cushion for the unaffected foot. This is to keep one leg from being longer than the other which would cause a person to walk abnormally and create other biomechanical problems (back pain, joint pain, etc.).
