Features & Benefits:
- Four-Points of Leverage Dynamic System
- This patented technology was developed to reduce the strain on the ACL by distributing the load placed on the ligament via four points.Click here to learn how the Four-Points of Leverage works.
- FourcePoint Hinge Technology (Stop kit not included)
- 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.
- Adjustable Extension Resistance
- The FourcePoint Hinge enables you to set the flexion angles (25˚, 35˚ (factory setting), 45˚, 55˚, or 65˚) based on your condition or point of recovery. This puts you in control where the degree of tension stops.
- Available in Standard and Short Calf lengths (Ski/Snowboard Boot and Motocross Compatible)
- Now you can choose the calf length to further customize the fit of your knee brace. The short calf length is recommend if you will be wearing ski boots or similar items at the same time as your knee brace.
- Aircraft Aluminium Frame
- You get the benefits of a lightweight and low profile knee brace that is also stronger, thicker, and more stable than the other lightweight knee braces on the market.
- Anti-migration Supra Condyle Pad
- Your knee brace will stay in place no matter how active you are.
