  • LowProFourcePoint Hinge Technology : Makes you less likely to suffer from an ACL injury because it reduces the amount of time your knee is in an "at risk position", enhances the Four-Points of Leverage by increasing the posterior load applied by the brace on the tibia, and improves your natural gait by applying progressive resistance before reaching a firm end point during movement.
