UNDER ARMOUR MEASUREMENT GUIDE

HOW TO MEASURE:

Foot - Under Armour starts with the true foot, which means they measure from heel to toe. That measurement (in centimeters) is then translated into Under Armour's standard sizes.

To find your foot measurement closely trace your entire foot onto a piece of paper and measure from heel to toe. If your measurement is between chart numbers, Under Armour recommends sizing up.
