Sizing and Fit
How to Choose the Correct Ankle Sleeve Size
Choose an ankle sleeve size from your ankle circumference, measured about 2 inches (5 cm) above the ankle bone. That measurement describes the part of the leg the sleeve fastens around. Sizing is unisex.

Both units are published so the choice can be checked rather than estimated: M is 7.5 to 9 in (19 to 23 cm), L is 9 to 10.4 in (23 to 26.5 cm), and XL is 10.4 in (26.5 cm) and up, with no upper limit.

- 3If you sit exactly on a boundary, choose the smaller size for a tighter, firmer fit or the larger size for a looser fit.
What the fit should feel like
KnitPair is designed to feel firm and even around the ankle and midfoot, with the strap fastened flat. It should remain in place rather than bunching, folding or rolling.
If the fit feels uncomfortably tight, remove the sleeve and recheck both your measurement and the size printed on the order.
