Understanding the Size System for Ski Boots
Ski boot sizing is not the same as regular shoe sizing, so don't be surprised if the numbers you see are a bit different from your normal street shoe size. The sizing for ski boots is called mondo sizing and refers to the length of the foot in centimetres (EX: 27/28/29). Ski boots are marked with the size and the half size, so you will find both sizes on the same boot.
