Tuli's The X Brace is a simple yet highly effective elastic foot support. Its beauty and effectiveness lie in its ease of use, simplistic design, and incredible success in providing arch and heel support.

Unique Design

Tuli's The X Brace offers elastic arch support with a unique 'X' design that helps enhance foot stability and reduce arch and heel pressure. Its low-profile design allows comfortable wear with any footwear or even barefoot, making it ideal for individuals seeking additional foot support. Commonly used by those researching foot care topics such as plantar fasciitis, Sever's disease, and over-pronation.

The X Brace arch support also effectively helps to maintain proper foot alignment due to under-supported, overused feet, making it an ideal choice for foot support to wear with sandals or even barefoot.

• Unique "X" design for foot support  
• Wear with sandals, socks, shoes, or barefoot
• All the benefits of taping without all the time and tape
• Includes integrated silicone strip on the heel to keep it in place
• Sold as a pair
  

Made in the U.S.A.

For optimal results, we recommend wearing Tuli's The X Brace initially for a few hours daily. Gradually increase the usage up to 12 hours per day as needed. It can be worn during or after activities, with or without shoes or socks. However, it is not recommended to wear it while sleeping.

Tuli's® The X Brace® and The X Brace +PLUS™ 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. 

Size Chart:

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.

What happens if my Tuli's The X Brace slips?
The only reason that our third generation of Tuli's The 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 The 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 The X Brace?
There is a normal break-in period whenever a new The 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.

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.

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

HSA/FSA Questions:

What is Flex and what is their relationship with Medi-Dyne?
Medi-Dyne has partnered with Flex to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA). This means you can now use your HSA or FSA debit card to buy Tuli's The X Brace with pre-tax dollars, resulting in net savings of 30-40%, depending on your tax bracket.

How do I pay with my HSA or FSA card?
To use your HSA or FSA debit card, add products to your cart as usual. At checkout, select “Flex | Pay with HSA/FSA” as your payment option, enter your HSA or FSA debit card, and complete your checkout as usual. If you don’t see “Flex | Pay with HSA/FSA,” you may be in Shop Pay. Select “checkout as guest” to view more payment options.

What if I don’t have my HSA/FSA card available?
If you don’t have your HSA or FSA card handy, still select “Flex | Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.

Why can’t I see Flex as a payment method? (For Shopify Partners only - please remove this italicized blurb when adding to FAQs)
The key here is to make sure you are logged out of ShopPay. One of the easiest ways to do this is to go through checkout in an incognito window.

Why is my HSA/FSA card being declined?
HSA/FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.

I submitted my Flex itemized receipt for reimbursement and my FSA requires more information.
Please forward us the request from your FSA, and we will work with the Flex team to issue you a new receipt.

Help! I didn’t receive an email from Flex with my itemized receipt and/or letter of medical necessity. What should I do?
Please check your spam folder, as sometimes emails from notifications@withflex.com may be automatically filtered as spam by some email service providers. If you still can’t find it, please email support@withflex.com and let them know the email address associated with your order.

I would like to use multiple HSA/FSA cards to pay for an item. Can I do that?
No, unfortunately, this isn't a supported feature right now. If there are insufficient funds in a single HSA or FSA account, you can instead enter a credit card on the Flex checkout page. You will receive an itemized receipt and/or Letter of Medical Necessity from Flex, which you can submit for reimbursement.

My purchase receipt from Medi-Dyne has a different number than what my FSA was charged. How can we resolve it?
Thanks for reaching out, and apologies for the discrepancy. We'll review the charges and get back to you with details of the likely refund shortly.

Is sales tax covered by HSA/FSA funds, or is it treated separately?
Sales tax for eligible items is also covered by HSA/FSA funds. If the customer has a split cart, the tax will be divided among the cards based on the items.

HSA/FSA Reimbursement Questions:

My HSA/FSA Claim was denied. What should I do?
We strongly recommend checking with your HSA/FSA provider to see if a purchase is eligible prior to completing the purchase. However, if you believe your claim has been wrongly denied, please send over any response from your HSA/FSA provider to us so we can share it with Flex and receive guidance on the next best steps to take. Please note that employer-sponsored FSAs can determine what products are eligible beyond the IRS’s guidelines, so it’s extremely important to check prior to purchase.

Can a customer purchase a product now and apply for FSA reimbursement in the next calendar year?
The ability to apply for FSA reimbursement in a future calendar year depends on the policy of the specific FSA provider. Most FSA administrators require that the purchase be made during the time of coverage. For example, if the FSA coverage is for 2025, all purchases typically need to be made and/or submitted for reimbursement within that coverage period.

However, some administrators may have more flexible rules regarding the timing of when the expense occurred. We recommend that customers review their plan policy to confirm the details.

Note: Health Savings Accounts (HSAs) are different and generally allow for reimbursement at any time, even in future years.

Can old (non-Flex) customers use their order confirmation email to apply for HSA/FSA reimbursement?
Unfortunately, for purchases made without using Flex in the checkout to receive an itemized receipt, it may be difficult to apply for reimbursement.

For Health Savings Accounts (HSAs), consumers can use an itemized receipt for reimbursement anytime after they have made the purchase, even if it is many years later.

For Flexible Spending Accounts (FSAs), most accounts require that the purchase was made in the calendar year during which the consumer had the FSA, as FSAs typically do not roll over. Some FSAs offer a buffer window, allowing customers additional time to submit receipts for expenses incurred during the previous calendar year.
