Trusted By Athletes
The IFAST has been rigorously tested in the lab and is trusted by thousands of athletes and teams, all counting on the IFAST to protect their ankles without restricting their performance.
Built from Anatomy
FAST stands for Functional Anatomical Stabilizing Technology. This methodology is inspired by the body to move the way athletes move and protect the way the body protects. The primary three parts of the IFAST are designed to mimic a part of the body.
Part 1: Tension System | Ligaments
Incorporated into the IFAST is a synthetic ligament. Using specially selected materials, the tension systems behave like the ligaments in the body. Built into the tension system is an adjustable tension cord that allows for a customizable level of support.
Part 2: The Cuffs | Bone
Built for Protection
The IFAST uses an upper and lower cuff to secure the device to the ankle. By using a material slightly more sturdy then the tension system, these cuffs act like the bone and keep all motion and protection focused at the ankle joint.
Part 3: Compression Sleeve | Skin
Keeping the body protected and compressed is the skin. The IFAST compression sleeve acts as the skin, surrounding the ankle joint, keeping it warm and mobile.
