The width of the ski boot is crucial for an optimal fit. A boot that is too narrow can cause discomfort, while one that is too wide does not provide sufficient contact and support for the ski.
Narrow fit’ ski boots have a forefoot width of 98 millimetres (in MP size 26/26.5) and, in general, are more snug-fitting. They are designed for skiers with narrow feet and for those who want a sporty fit for maximum power transfer.
A ‘medium fit’ has a minimum width of 100 millimetres (in size MP 26/26.5). These medium width ski boots are slightly wider at the midfoot and heel, and are suitable for most skiers.
Ski boots with a ‘wide fit’ have a minimum width of 102 millimetres at the forefoot (MP size 26/26.5). These wider-cut ski boots are aimed at skiers with wider feet and calves.
