High 5 Size Chart

Your ankle brace size is different from your shoe size because itโ€™s based on your ankle circumference. View our size chart for instructions on measuring your ankle circumference. Youโ€™ll use that measurement to figure out which size brace will provide the best fit.

Size Chart

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 in-between two size we would recommend going with the smaller size. For example, if your ankle is measuring right at 14โ€ then we would recommend going with the size Medium.

The Ultra High-5 is built for individuals dealing with chronic ankle instability who need a solution they can rely on long-termโ€”not just temporary relief.

Unlike compression sleeves or lace-up braces that rely on tension and compression, the Ultra High-5 uses a rigid, bilateral structure to help keep the ankle secure during everyday movement.

Its low-profile design fits inside low-top work boots, hiking shoes, and everyday footwear, making it a practical option for long hours on your feet, uneven terrain, and daily routines where your ankle needs to hold up.


Stronger Than Sleeves & Lace-Ups

Compression sleeves and lace-up braces rely on tension and compression to create a temporary feeling of stability.

The Ultra High-5 takes a different approach, using a rigid structure to provide a more consistent solution for those who need long-term ankle stability.


Controls Side-to-Side Movement

The Ultra High-5 uses a rigid shell and bilateral hinge design to help limit side-to-side ankle rolling.

At the same time, the hinge allows natural up-and-down movement, so you can walk comfortably without feeling restricted.


Built for All-Day Wear

The Ultra High-5 fits comfortably inside low-top work boots, hiking shoes, and everyday footwear.

Its single-strap, hook-and-loop design stays secure throughout the day without constant readjustment, while also making it easy to put on and remove.


Constructed for Long-Term Reliability

The Ultra High-5 features a structurally sound, rigid design that delivers dependable stability for daily use.

It provides consistent reinforcement over time, making it a reliable option for work, walking, and uneven terrain.


Who Is the Ultra High-5 For?

  • Individuals dealing with chronic ankle instability
  • Active adults who want more confidence in everyday movement
  • Workers who spend long hours on their feet in boots or work shoes
  • Those who spend time on uneven terrain, including hiking and outdoor activity

Frequently Asked Questions

Question: Why can the Ultra High-5 initially feel uncomfortable?

Answer:ย Like a new pair of shoes, the Ultra High-5 requires a short break-in period. We recommend wearing the brace inside your shoes for 15โ€“20 minutes at a time to allow it to mold to your ankle. For best results, follow ourย Custom Form Fitting Videoย for a faster, more personalized fit. Take time to wear it and allow it to form to your ankle for the best fit and performance.


Question:ย Why does the Ultra High-5 feel loose or unsupportive when I first put it on?

Answer:ย The Ultra High-5 is designed to provide full support and stability only when worn inside a properly laced shoe, low-top work boot, or hiking shoe โ€” not sandals, tall boots, or slip-on styles. Once inside a proper shoe, the brace locks into place for maximum stability and comfort.


Question:ย The Ultra High-5 is an orthopedic ankle brace. What does that mean?

Answer:ย As an orthopedic-grade brace, the Ultra High-5 offers a higher level of ankle stability than typical compression or lace-up braces. Its hinged design mimics natural ankle motion while stabilizing against harmful side-to-side movement. Like many orthopedic products, it requires a short break-in period. โ€“ Watch ourย Custom Form Fitting Videoย to learn more.


Question:ย Can I wear the Ultra High-5 on either ankle (left or right)?

Answer:ย Yes โ€” the Ultra High-5 is initially universal and can be worn on either ankle. Once form-fitted to one side, it becomes customized for that ankle. We recommend labeling it โ€œleftโ€ or โ€œrightโ€ after fitting. โ€“ Watch ourย Ultra High-5 Fitting Videoย for step-by-step guidance.


Question:ย Can I use the Ultra High-5 for Hiking?

Answer:ย Yes. The Ultra High-5 performs well on uneven terrain and fits comfortably inside most hiking shoes and low-top hiking boots, making it a great option for uneven terrain and outdoor use.


Question:ย Do I need to wear socks with the Ultra High-5?

Answer:ย Yes. For comfort and hygiene, we recommend wearing crew-length or athletic socks with the Ultra High-5 โ€” just like with most ankle braces.

We are very happy with the ankle braces. ย Our high school son wears them for basketball. He was having recurrent ankle sprains in lace up braces. He is a giant child (6โ€™7โ€, 260#) so the Ultra Ankle braces support him much better. ย He has come down from jumping and landed on other players feet but in the Ultra Ankle braces he has not had an injury. ย Thanks!

My daughter plays volleyball and has been recovering from tendinitis and a previous ligament tear she received from coming down on top of someone’s foot that drifted under the net. She used to wear lace up ankle braces. We switched when our doctor suggested that the lace up ankle braces could possibly be contributing to her tendinitis. The braces were immediately used with minimal break in needed. She said they were comfortable, easy to use, and she felt supported. On Sunday another player drifted under the net and my daughter was blocking her. My daughter landed on the girl’s foot but this time she felt the brace support her ankle and she all she had was a little soreness as opposed to a ligament tear this time! Thanks for your suggestion to purchase the High-5. They are perfect!
