Place a sheet of paper on the floor and against a wall.
Make sure you are wearing the same socks that you would normally wear with this type of shoe or boot.
Wearing these socks, stand on the sheet of paper with your foot perpendicular to the wall and your heel against the wall.
Then use a pen to draw a line just in front of your big toe. Repeat for both feet and take the longer distance to determine your size.
Using a ruler, measure the distance between the wall and the line you drew to find your size.
Once you've got your length in millimeters, you just have to report it in the corresponding cell of the column "foot length range (mm)".
Note: To find out your foot width, do the same but using the outside of your foot against the wall. If the width is more than 107mm (4.21"), your foot is wide. To have a better fit, you can: order the wide version of the model if it is available, or you can add +0.5 to your order size.
