Your ankle brace size is different from your shoe size because it’s based on your ankle circumference. View our size chart for instructions on measuring your ankle circumference. You’ll use that measurement to figure out which size brace will provide the best fit.
Measure around your ankle with a tape measure as shown in the photo and then reference the size chart to the right. If your ankle is measuring right at 14" then we would recommend going with the smaller size.
| SIZE | IN | CM |
|---|---|---|
| S/M | 10.5in – 14in | 26.5cm – 35.5cm |
| L/XL | 14in – 16in | 35.5cm – 40.5cm |
The Ultra CTS® is designed to help reduce stress on the ankle joint by unloading weight during movement. This helps minimize the impact and pressure that can cause pain—especially in cases of ankle arthritis or bone-on-bone irritation.
Instead of simply supporting the ankle, the Ultra CTS helps absorb and redistribute force, allowing you to move more comfortably throughout your day.
Not just support — designed to reduce joint stress with every step.
Most ankle braces are built to support ligaments after a sprain—but they don’t address joint pain caused by arthritis.
The Ultra CTS is different.
It is specifically designed to help reduce joint loading, which is one of the main sources of pain for people dealing with ankle arthritis. This makes it an effective option for those experiencing discomfort while walking, standing, or performing daily activities.
The Ultra CTS uses a dual-shell, hinged design to:
This combination helps reduce stress on the joint while still allowing you to stay mobile—something traditional braces often cannot do effectively.
Most ankle braces are designed to limit motion or add compression after an injury. The Ultra CTS is different.
Rather than simply bracing the ankle, the Ultra CTS is engineered to reduce the amount of weight your ankle has to bear during movement. By unloading the joint and redistributing force away from painful areas, it helps reduce discomfort while still allowing natural movement.
This makes the Ultra CTS a true unloading ankle brace — not just a support or compression brace.
Question:
Will this help with ankle arthritis pain while walking?
Answer:
Yes. The Ultra CTS is designed to reduce weight-bearing stress on the ankle, which is a primary source of pain for individuals with ankle arthritis. By unloading the joint and redistributing force, it helps make walking and daily movement more comfortable.
Question:
Why does the Ultra CTS feel uncomfortable at first?
Answer:
This is normal. The Ultra CTS is designed to reduce weight-bearing stress on your ankle, which creates a different feel compared to traditional braces. Like a new pair of shoes, it requires a short break-in period to begin forming to your ankle and walking pattern. Watching our Custom Fitting Video can help quicken this process.
Question:
How long does it take to break in the Ultra CTS?
Answer:
Most users adjust within 2–3 days of regular wear. We recommend starting with shorter wear sessions (15–30 minutes at a time) and gradually increasing as your comfort improves. As the brace forms to your ankle, it will feel more natural during movement.
Question:
Why does the Ultra CTS feel bulky or different when I walk?
Answer:
The Ultra CTS is not a typical ankle brace. It is designed to help reduce stress on the ankle joint, which can change how your foot and ankle move during walking. This difference is expected and becomes more comfortable as you adjust to the brace. Watching our Ultra CTS Fitting Video will help you adjust to the brace faster.
Question:
Is the Ultra CTS supposed to reduce pain right away?
Answer:
Some users notice relief quickly, while others experience improvement over time as they adjust to the brace. The Ultra CTS works by reducing joint stress during movement, so consistent use is key to experiencing the full benefit.
Question:
Do I need to wear the Ultra CTS with shoes?
Answer:
Yes. The Ultra CTS is designed to function properly when worn inside athletic shoes. This allows the brace to stabilize and support the ankle correctly during movement.
Question:
Can I wear the Ultra CTS all day?
Answer:
During the break-in period, we recommend wearing it in shorter sessions and gradually increasing wear time. Once adjusted, many users wear it during daily activities, walking, or extended periods on their feet.
Although your new ankle braces will fit either ankle when you get them, make sure to mark them “right” or “left” on the white tab on the upper strap and wear them on the same ankle each time. Since the ankle braces will form fit to your ankle, they will become specific to one foot after you break them in.
“I had a double leg fracture near the ankle and my leg was dislocated so I tore a bunch of tendons, ligaments, etc. My orthopedic surgeon recommended your brace. I wear it all day long and it is helping. I have played racquetball twice in the last two weeks. It seems to give me great support but allows me they mobility I need to play the sport. Also, it goes on so quick and easy which is nice.”

“I purchased the Ultra Ankle after my daughter sprained her ankle playing capture the flag. Unfortunately, it was 2 days before her soccer season started and she was devastated when she heard it was a high ankle sprain. I expressed mailed the brace so she could start using it as soon as possible. Once she put it on, it was amazing. She went from being able to put no pressure on her ankle to being able to walk normally without crutches. She said it was a miracle. You should have seen the smile on her face. I have no doubt that the ultra ankle has been the reason for her very quick recovery. She will be resuming soccer after just 3 weeks which is very, very quick with a high ankle sprain. Thanks for making such a fabulous product.”

“First off, your product is far superior to any other ankle brace I have used (which is a lot). My surgeon approved me to use it instead of the lace up, and my physical therapist loves it. I’m still in a boot “ween” program, but my ankle feels significantly better in the brace. “
Wallace G.
“My daughter loves her ankle braces. She rolled her ankle bad back in May and at the AAU nationals in Orlando there was a booth and she tried them on there and fell in love. We had tie up braces and she threw them out after wearing these. We have the Ultra CTS for her bad ankle and the zoom for the other ankle. She plays volleyball and uses them every practice and game. I love how it allows the ankle to move naturally without letting it roll.”

Lessen weight bearing pain caused by an acute ankle injury or a condition such as osteoarthritis by reducing the impact on your joint. The Ultra CTS is the only ankle brace that helps lower pain by absorbing some of the painful impact normally transferred to your ankle joint. With less pain you’re able to focus on increasing your activity and shorten your recovery time.
The Ultra CTS is used extensively by physicians and sports medicine professionals with patients when they transition from a walking boot to active rehabilitation because it provides a full, natural range of motion and helps you regain flexibility and strength.
The Ultra CTS is considered a custom treatment system because it transitions with you during your recovery from an acute ankle injury. Detach the upper cuff portion of your brace to transform it into a low-profile activity brace once you’re ready for increased mobility. This ensures your investment lasts through every stage of your rehab, protecting you from the sidelines to the starting lineup.
