Developed for skiers looking for a comfortable boot that easily adapts to the shape of their feet, Salomon’s S/PRO ALPHA 100 offers a new level of fit and performance. Featuring an easily customizable shell and liner, this 98 mm boot delivers a strong heel lock without adding unnecessary pressure on your instep.

For skiers that can comfortably ski across the whole resort and are keen to get better on icy slopes and in variable conditions.

A flex rating between 100 and 130 for women, and 110 and 140 for men, ideal for advanced-level skiers and those whose morphology requires more sturdy support. A last width < or equal to 99 mm (MP 26./26.5) is ideal for skiers with narrow feet and those looking for a tighter fitting, more reactive boot. To identify one's preferred last, the foot's width between the first and the fifth metatarsal bone is measured to gather an overview of the skier's natural foot shape and volume.
