The X Brace is available in multiple sizes. Use the chart below to determine the correct X Brace size according to your U.S. shoe size.

To find the best support measure your arch circumference right below ball of foot and follow chart arch measurements below. 

Please Note: If your arch measurement is different from your shoe size select the appropriate size for your arch measurement.

Children under the age of 16 that are wearing adult size shoes inevitably have a smaller arch.  If your child’s adult shoe size lands right on the edge of one of our adult sizes the smaller X Brace is usually the correct choice.

If you have an extremely wide or narrow foot and would like additional information about sizing please don’t hesitate to contact us.

Tuli's The X Brace is a simple yet highly effective elastic foot brace and a premier treatment for heel pain associated with plantar fasciitis, Sever’s disease and over-pronation.

An Effective Solution

The beauty and effectiveness of the Tuli's The X Brace lies in its ease of use, simplistic design and its ability to address very complex issues with incredible success. Heel pain due to plantar fasciitis, Sever’s disease and over-pronation are often caused by under-supported, over-use of the foot. The unique “X” design of our patented foot brace provides support and reduces arch pressure very similar to how Low-Dye taping works but without all the expertise, time and tape necessary. This support of the arch also helps offset over-pronation, effectively addressing what can be debilitating foot pain.


  • Helps to reduce or prevent heel pain and discomfort
  • Socks, shoes or barefoot, no problem; literally wear The X Brace with anything
  • All the benefits of professional taping without all the time and waste of tape
  • Integrated silicone strip on the heel strap for added comfort and grip. Sold as a pair


We recommend wearing The X Brace initially for a few hours per day and gradually increasing up to 12 hours per day as needed. May be worn during or after activities - with or without shoes and with or without socks. Do not wear while sleeping.

How to Care for your Tuli's X Braces.

The X Brace is NOT to be used by individuals with diabetes, neuropathy or vascular disease. If discomfort or pain results, persists or increases, discontinue use and consult a physician.

    Best Product for Severs

    My daughter is a gymnast with Severs Disease and these are a lifesaver. She used the size small until she outgrew them so we bought the mediums. Thank you for providing a quality product that actually works!

    Hi Maritza - We are glad to learn you are benefiting from our Tuli's The X Brace. Please feel free to contact us at 1-800-810-1740 if you have any questions.

    What happens if my Tuli's X Brace slips?

    The only reason that our third generation of Tuli's X Brace will slip is if the size is wrong or the wearer’s foot has an unusual shape that, regardless of size selection, will not allow The Tuli's X Brace to stay on. This does occur in a small percentage of people. Our third generation Tuli's X Brace has an integrated silicone strip running the entire length of the heel strap providing a secure grip on the heel.

    Why does my foot hurt when wearing the Tuli's X Brace?

    There is a normal break-in period whenever a new X Brace is applied. The foot is very sensitive to touch, and pain can be present when new things apply pressure to the foot. The muscles of the foot are also sensitive and with The X Brace’s revolutionary concept of helping the foot to work better, these muscles can cramp if they are not used to performing as they should. If cramping/pain occurs, remove the brace immediately and give your foot 15 minutes rest, then return The X Brace to your foot and resume activity.

    How do I put it on and what should it look like once I'm wearing it?

    The Tuli's X Brace main strap should be just below the ball of the foot, but worn where it is comfortable for you. The loop strap must cross over on the bottom of the feet, forming the “X” on your arches, and then hook onto the back of the heel. Once again, where you place the heel strap depends on your comfort level. We recommend not having it too high, as this might be uncomfortable for your Achilles’ tendon. See our video, below, to learn more about putting on The X Brace.

    Will the Tuli's X Brace fit in my shoe?

    Absolutely. The Tuli's X Brace’s low-profile design will fit into any shoe or cleat, and is comfortable to wear with any kind of footwear, flip-flops and high heels included.

    Why should I choose The Tuli's X Brace instead of a sole insert?

    The Tuli's X Brace offers the user something more than what the traditional treatments of foot pain, like a sole insert, ever could. An insert in your shoe provides increased padding and support for your foot, keeping your foot supported and molded correctly. The Tuli's X Brace focuses its pressure on the connective tissues and tendons in the middle of your foot, because that’s where most foot pain originates. Another distinct advantage that The Tuli's X Brace has is its compatibility. The X Brace fits in any shoe, whether it’s a high heel or cross-trainer, and it can be taken with you from shoe to shoe or simply worn barefoot. This type of support gives you the assurance that whether you’re on your feet or off, your pain is being addressed.

    How often should I replace my Tuli's X Brace?

    It is estimated that The Tuli's X Brace has approximately 200 hours of effective life before it will need to be replaced. If you’re using your X Brace during everyday workouts (4 + hours in the gym per day, five days a week), we recommend having two pairs of braces that you can wear on alternating days. This will allow the elastic to dry out and recover completely before being worn again, extending the life of both pairs.

    Can I wash the Tuli's X Brace?

    We definitely recommend that you wash your Tuli's X Braces. If you’re rotating between two pairs, wash them once a week. Hand or machine wash (gentle cycle) in cold water with mild clothing detergent such as 2Toms StinkFree Sports Detergent and air dry.
