How to measure your shoe size
Follow these steps to determine your shoe size. Do this during or at the end of the day for accuracy, as feet swell throughout the day.
1.
Place a piece of paper under your foot. Stand up straight and have your heel lightly touching against a wall.
2.
Mark the tip of your longest toe and heel on the paper. Measure the length of your feet from heel to toe.
3.
Repeat the steps for your other foot and compare the measurements with our size chart below.

For running shoes, we generally recommend sizing up a half size from your casual shoe size.
