Step 1
Place a sheet of paper on the floor with one end against a wall. Put your foot on the sheet making sure the heel is against the wall at a right angle. Use a ruler to measure the distance (in cm) from heel to toe.
Step 2
Mark the longest distance of your foot (heel to toe) on the paper with a pencil or pen. Repeat with the other foot, as left and right feet may have different measurements. If so, select the larger size.
Tips
Measure your feet barefoot or with the sock/stocking you would normally wear with the shoes. Distribute the weight evenly before measuring. Measure your feet in the afternoon, as feet tend to swell throughout the day.
