The ACR ROCKING SHOE allows to adjust or correct the P3 palmar angle according to its position more or less backward under the foot. Its special cross-sectional design ensures smooth landing and breakover. Its particular profile- thinner at the heel - allows a smooth landing (less impact) and the thinner toe eases the breakover in reducing stress on the tendons and ligaments during inter-phalangeal extension. It also improves the blood circulation in the foot.
