Salomon S/Pro Alpha 120 GW Ski Boots 2025

With the narrowest cuff in the business and Custom Shell HD heat molding at your disposal the Salomon S/Pro Alpha 120 GW Ski Boots deliver "right now" response and the ability to make very subtle turns with ease. Designed for narrow feet and ankles but easily made to fit most average feet with a heat mold, the S/Pro Alpha 120 has been a huge seller with the advanced-to-expert crowd, and we expect the trend to continue.

• 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  -  120 – A stiff flex suitable for advanced to expert level 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.
• My Custom Fit 4D Race Liner  –  Pre-shaped Race liner offers improved foothold & snug fit. Cushier foams & outside placement of the Talyn® fabric ease adaptation. The elastic toe box gives more forefoot space.
• Custom Tongue  –  Fully dismantlable and entirely customizable tongue allows for perfect instep height adaptation. You can add foams or remove materials where it's needed (+/-8mm).
• Shell  –  Polyurethane
• Cuff  –  Polyurethane
• 4 Micro-Adjustable Screwed Aluminum Buckles  –  45° buckle placement of the lower shell
• Power Strap  -  45 mm Screwed Energy Z-ER Velcro – This easy to remove 45 mm thick strap holds the lower leg securely in place and optimizes power transmission, while an elastic section enhances rebound and progressiveness.
