Achilles Tendonitis commonly occurs from shearing and stretching (tractional) forces placed on the Achilles tendon at the back of the heel. Excess Pronation causes the heel bone to tilt excessively and places extra strain on the tendon. Inflammation of the tendon is a common result along with tightening of the calf muscles.

The VAS Performance plus footbeds aligns the heel bone and significantly reduces the shearing and stretching forces on the Achilles Tendon, thereby providing relief from Achilles Pain.
