High 5 Size Chart

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.

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 14” then we would recommend going with the size Medium.

Your Ultra High-5 brace size is based on your ankle circumference. See our size chart link above or in the photo gallery to determine your correct size.

Protecting Natural Ankle Movement. Not Preventing It.

Traditional ankle braces were designed to restrict ankle movement—good or bad. While limiting ankle motion may seem like the solution, many people continued to experience repeated ankle rolls because the harmful motions that lead to injury weren’t being effectively controlled.

The Ultra High-5 was designed differently. Instead of restricting natural ankle movement, it helps control the harmful motions that lead to repeated ankle rolls while allowing your ankle to move naturally. The result is comfortable, dependable protection that gives you the confidence to walk, work, and explore uneven terrain.

Designed Around Your Ankle—Not Wrapped Around It.

Traditional ankle braces wrap the ankle joint, restricting both healthy and harmful ankle movement. As you walk throughout the day, they can loosen, shift, and require frequent readjustment.

The Ultra High-5 takes a different approach. Its external shell and hinge system work alongside your ankle rather than wrapping tightly around it, allowing natural ankle movement while helping control the harmful motions that cause repeated ankle rolls. Because it stays securely in place throughout the day, the Ultra High-5 provides dependable ankle support from the first step to the last.

Every Feature Has a Purpose

Hinge

Protects Natural Ankle Movement

Allows your ankle to move naturally through its normal up-and-down range of motion.

Semi-Rigid Shell

Helps Prevent Ankle Rolls

Single Strap

Easy On. Secure All Day.

A single adjustable strap makes the Ultra High-5 quick to put on while helping it stay comfortably in place throughout the day without constant readjustment.

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