Tested Performance

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.

Fast Technology

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

Customizable Support

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

Built from Anatomy

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.

    I just wanna say after two days I am already in love with these braces. I have been using ASO since 7th grade because I have had incessant ankle problems ever since I started sports, and I have never really liked wearing them. I would come off of a 3 hour practice, volleyball or basketball, and feel pain all around my ankle and fatigue in my legs more than usual. I found myself working endlessly to strengthen my ankle so I wouldn’t have to wear the braces during practices and games. Obviously, that wasn’t a choice for me, so I just had to tough it out. Using the IFAST braces over these past few days have made me feel so much more secure and comfortable during conditioning and practices. I love that I feel freedom, but also support in both of my ankles. Volleyball is a very shifty, fast moving sport, so I know these braces are going to help improve the way I play.

    The brace works well for me so far. I like that it is smaller than most ankle braces I’ve worn. I am using it for running which most braces are too big or too stiff and wearing to work. No issues so far. I was recommended the brace by a friend who is an athletic trainer, she has used them with her athletes and said they liked it a lot.

    I just wanna thank you guys for the braces! They’re by far the best I’ve ever had. After spraining my ankle three weeks ago thinking I wouldn’t be able to cut and run, the ankle braces gave me a lot more support than I thought and helped me tremendously in being able to run and cut! I use them everyday when I workout and when I’m running or doing football drills. You guys did a great job of making it fit almost like a shoe. I can’t really tell I have it on sometimes because it feels like it’s a part of my cleats or shoes I’m wearing. It gives great support and is the best ankle brace I’ve worn yet. Thank you guys so much.

    The IFASTs are a life saver! I sprained my ankle multiple times in junior high and once I started wearing the IFAST I didn’t have a single ankle injury for 4 straight years of high school basketball!

    Last year we used the ARYSE ankle braces for our basketball team and the players loved them! They were much more durable and comfortable than the bulky lace up braces we had used for years. The price point of their products established through the partnership with NJCAA has been great for our budget as well. We are sold fully on ARYSE products.

    These braces are the best I have ever used! I’m a member of the US Special Operations community and a kinesiologist as well, and the design of these braces is brilliant. I tell all of my teammates about these, and the physical therapists we have love them as well. If you’re on the fence about purchasing these braces, don’t be. Do yourself a favor and order them now!

    These braces have helped so much!! I need surgery on one of my ankles, but its not an option right now as I work in health care and are low staffed! My surgeon recommended these to get me by until I could have it done and I’m glad he did!! I am Not a brace fan, but these have been a life saver for me in a time like this…Well worth the money.

    This is easily a hundred dollar brace! I have an an ankle at around 70% from an old injury, and it regularly makes itself known! The iFAST is so minimal, natural, and unnoticeable that its a welcome addition to my life. Seriously if I had to send another 50 to keep it, I would in a heartbeat!

  16. Kaden Tyler Jolley (verified owner)

    If you want a comfortable ankle brace that somehow still allows a lot of support, look no further and buy the IFAST. I’ve used them a few times while playing basketball and it gives me a lot of confidence to ball out without worrying my ankles will snap in half.

    I couldn’t have asked for a better ankle brace. Shoutout to ARYSE for making this superior performance bracing available to me. I will never use another brace. Thank you ARYSE!
