An adjustable ankle brace for sprains, rolled ankles, and the kind of lingering instability that makes you think twice before every step. Slim enough to wear inside a sneaker, boot, or work shoe — so support doesn't mean changing your day.
H-shaped SBR cushion — targeted support on both sides of the joint to steady a weak or recovering ankle and cut down on fatigue through the day.
Quick-release straps — on and off in seconds. No unlacing, no rethreading, whether you're mid-workout or heading out the door.
Breathable and light — 4.8 oz of moisture-wicking material that stays cool over long wear.
Low-profile fit — full coverage without the bulk, so it disappears inside most footwear.
Side-specific shaping — built for the left or right ankle rather than a compromise between the two, in three adult sizes.
Find your size
Measure around your ankle at its narrowest point, just above the ankle bone.
Size
Ankle circumference
XS / S
7" – 8.6"
M / L
9" – 9.8"
XL / XXL
10.2" – 11"
If your measurement falls between two sizes, choose the larger one — the straps take up the slack, and a brace that's too tight is the most common reason people stop wearing one.
Left or right? Each brace is side-specific, so order for the ankle you need to support.
Often FSA/HSA eligible — eligibility depends on your plan, so check with your plan administrator. Designed to support recovery from ankle sprains and to help protect against re-injury; it isn't a substitute for care from a healthcare provider.
Size Guidance
Two quick steps. First, size by shoe size or foot circumference: XS/S fits Women's 4.5–8 / Men's 3.5–6.5 (foot 7.0–8.6"), M/L fits Women's 8.5–11 / Men's 7–9.5 (9.0–9.8"), XL/XXL fits Women's 11.5–14 / Men's 10–12.5 (10.2–11.0"). Near the top of a range? Size up. Second, order Left or Right to match the ankle you are bracing. Wrong size? Tell us within 24 hours of ordering and we'll change it free before it ships. After that, most fit issues are fixed without sending anything back — see our return policy for the options.
