Do Under Armour kids' shoes run big, small, or true to size?

How To Measure

FOOT: Start with the true foot, which means to measure from heel to toe. That measurement (in centimeters) is then translated into the 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, we recommend sizing up. Be sure you're putting your full weight on your foot while tracing. Please note: for the best results, measuring later in the day is recommended.

Use this easy-to-use sizing chart so that finding the right size shoes for your kids won’t be a workout in itself. *Due to the metric/imperial conversions, there will be some instances where two US sizes will equal one UK size or one CM size.

How to measure without a ruler or tape measure?

If you don't have a ruler or tape measure handy, you can try to measure with a standard credit card, which has a width of 3 ⅜ inch or 8.56 cm and a height of 2 ⅛ inch or 5.4 cm.

If you do a lot of online apparel shopping, accurate body measurement using a tape measure is a must. The actual tape you choose doesn’t matter that much. This retractable one is very easy to use, and the fact it uses both CM and IN is extremely helpful.
