Measured in millimeters, the volume refers to the last, or width, of the boot. Narrower boots are best for expert, aggressive skiers, who care more about performance than comfort. Foot width factors in as well, with narrow-footed skiers prefering boots with narrower lasts. Keep in mind that in general, the narrower the boot the less comfortable it will be.
