How to measure your feet

STEP 1
On a hard surface, tape a piece of blank paper to the floor. Stand up straight with your foot on the paper. Your heel should be barely touching the wall or not at all. DO NOT push heel into the wall as it will produce incorrect length measurements.

STEP 2
Mark the longest part of your foot (heel-to-toe length) and widest part of your foot on the paper with a pen or pencil. If your heel is away from the wall trace around your whole foot. Make sure your pen is held vertically, not at an angle. Repeat with the other foot, as the right and left foot may be different sizes.

STEP 3
Use a ruler to measure the heel-to-toe length and width measurement for each foot. Take these measurements and input them into the size calculator or compare them to the size chart below.
Note: This is a guide and may not work for all feet.
Size Chart
Please refer to the chart below for the approximate size conversion of foot length in mm to Bont size. If you have a narrow or wide foot please send us the drawing of your feet with length and width shown. The size Chart relates to other models such as the Jet and Semi Race III
