Salomon Women's S/Pro Alpha 90 W GW Ski Boots 2025

Salomon made the wise decision to bring their narrow fit S/Pro Alpha to the ranks of intermediate and lighter skiers with the Salomon S/Pro Alpha 90 W GW Ski Boots and it was a great call. For skiers with narrower ankles and feet (or even average feet with narrow ankle structures), the S/Pro Alpha heat moldable last is MONEY, giving you the most precise fit you've ever experienced which will translate to better skiing right away.

• Last  -   98 mm – Narrow last for slim to normal width feet with normal volume. Can be heat molded using the custom heat molding process to approximately 104mm in the forefoot.
• Custom Shell HD  –  Salomon's proven heat molding process makes boot fitting most feet quick and easy - the latest Custom Shell HD version is even quicker to mold than before. The thinner wall construction and new shell materials allow the foot to be closer to the shell and provide enhanced sensations, more power and direction energy transmission.
• 3D Instep Shell  –  This new construction refers to the construction of the lower shell. The thinner plastic and strategic positioning of the forefoot buckle deliver less pressure on the top of your foot, make for easier step in and out, and ensures stronger heel lock without putting unnecessary pressure on your foot.
• Flex  -  90 – A medium flex for intermediate to advanced skiers
• Flex Adjuster  –  The Flex Adjuster allows you to boost or smooth your flex.
• Power Spine  –  This metal plate links the cuff and the shell to provide strong back support, progressive rebound out of the turn, and powerful forward flex no matter the snow conditions.
• Liner  -  My Custom Fit 3D Performance
• Shell  –  Polyurethane
• Cuff  –  Polyurethane with Custom Shell HD
