To find your foot length, you'll want a piece of paper, a pen/pencil, and a ruler. Place the paper against the wall, and stand on it with your heels touching the wall. Use a pen/pencil to mark where the tip of your longest toe is, and use a ruler to determine the length.

Millimeters are used for better precision, divide the length in inches by 25.4 to convert to millimeters.
