How to get the right fit

First, don't measure your feet in the morning; feet often swell during the day due to heat and activity. For the best fit, measure your feet at the end of the day.

Step 1

Stand up straight on a hard surface with your heel against the wall and a piece of blank paper taped to the floor, flush against the wall beneath your foot.

Step 2

Have someone mark the longest part of your foot (referred to as heel-to-toe length) on the paper with a pen or pencil, or measure yourself if necessary. Repeat with the other foot, as right and left sizes may be different.

Step 3

Use a ruler to measure the heel-to-toe length you marked for each foot.
