Unmatched Protection

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 signature strut is a custom fit mechanism that forms to the ankle - shown here Left side from small to extra large, then extra large to small of the Right ankle strut




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.

R3 Ankle Brace is shown integrating with several types of athletic footwear like cleats and trainers, some athletes prefer to wear R3 inside the shoe, others wrap the straps around the outside of their footwear, center image shows the R3 brace on an anatomical foot model depicting the major foot bones, muscles and tendons

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

The R3 Pro HD Ankle Brace is displayed on a socked foot - the main component is the smooth ergonomic strut that is strategically held in place by two straps

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.

  • Is the R3 strut moldable?
    Yes! The strut is made to be custom molded using hot water. Detailed instructions are provided with every R3 Ankle Brace.
  • Is the R3's top strap adjustable in lenth?
    Yes, the top strap has 3" of adjustability based on the attachment configuration. Refer to the detailed Sizing Guide for best fit. All unused products are eligible for exchange within the first 30 days in case you need a different size!
  • What is the best way to integrate R3 into footwear?
    The preferred method is to place the bottom strap and strut foot plate under the insole of the shoe - keeping the upright segment between the shoe's toungue and laces. This is dependent on the type of shoe and wearer. The best way is to use it how it's the most comfortable fit.

I love the science behind this brace.

It’s why it works best and why

it’s my brace of choice.
