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. The Ultra Zoom will not fit a shoe size smaller than a women’s size 6 or a men’s size 7.
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. If your ankle is measuring right at 14” then we would recommend going with the size S/M.
