The R3 provides more than 2X the ankle roll resistance at 1/2 the weight of old style supports

with full normal motion intact.

Not Ankle To protection


R3's sleek strut is a match to ankle geometry, providing an advanced fit, feel and function far superior to old style lace up and stirrup supports. A few periods of wear mold the R3 into a custom fit that integrates well into most footwear.




The R3 protects without compromising ankle motion and enhances reflex response “You forget it’s there until you need it” is the confident remark of many users.


the R3




Resisting ankle roll is the most important function of ankle

protection. R3's dynamic roll resisting reflex & mechanical end range of motion stop check ankle roll to prevent or minimize ankle injuries in that critical split-second.

anatomy of the R3

R3’s injection molded thermoplastic strut

is the heart of the system. It’s dynamically engineered for a Rapid Reflex to lateral ankle roll (inversion), diverting force away from oft injured structures. Its low profile allows for shoe integration, further enhancing performance. It can also be integrated into a lace up support, which, vastly improves its performance. The flex modulus of the strut, i.e. stiffness, is calibrated in three variations, Sport (Standard), Pro HD (Heavy Duty) and Hero (Extreme). Considering the wearer’s physical stature, sport or activity, position, footwear, playing surface, injury status, gender and activity’s duration and intensity in the selection process will optimize R3’s fit, feel and function. It’s the first off the shelf custom in the category.
