This is how you can measure your foot in centimeters to choose the right size. Make sure you are measuring your bigger foot. Please use the same method for width of your foot. We need the measurement like the picture. 

WBSJ Size Chart 

* If you want to wear with thick socks or insoles, we recommend choosing one size bigger.

As an example... One staff member's foot size is 25cm, and size M of WBSJ was perfect when worn with regular socks. However, when she put WBSJ support insoles in them, they were a little tight. So she decided to go with size L boots.

If you are still not sure, please contact us with your measurements. We will be happy to assist you!
