Precision Meets Comfort for Advancing Skiers
The Salomon S/Pro Alpha 100 GW Ski Boots are built for intermediate to advanced skiers seeking performance without sacrificing comfort. With a narrow 98mm last and fully heat-moldable Custom Shell HD construction, the S/Pro Alpha 100 delivers a precise fit that adapts to your foot shape. Salomon’s innovative 3D Instep Shell reduces pressure over the top of the foot for easier step-in and improved instep comfort, while a 100 flex rating ensures confident control across varied terrain.
Designed with a strong but forgiving flex, these boots help progressing skiers explore steeps and carve groomers with responsive energy transmission and reliable heel hold.
