Salomon S/Pro Alpha 120 GW Expert Line Ski Boots 2025

Designed for advanced skiers looking for maximum control and a precise fit, the Salomon S/Pro Alpha 120 ski boots combine high-performance alpine technology with exceptional customization options. Built around a 98 mm last, this boot delivers a secure heel hold, progressive flex, and powerful energy transfer while reducing pressure on the instep.

Featuring Salomon’s innovative 3D Instep Shell, a fully customizable tongue, and a thermoformable Custom Fit™ 4D liner, the S/Pro Alpha 120 adapts to the unique shape of your feet for a personalized fit that enhances comfort and responsiveness all day long.

Precise Instep Comfort

The redesigned shell construction uses thinner plastic in key areas and strategically positions the second lower buckle at a 45° angle to reduce pressure across the top of the foot. This makes the boot easier to put on and remove while maintaining a secure, performance-oriented fit.

Enhanced Heel Hold & Stability

The 3D Instep Shell technology works with the 45° forefoot buckle positioning to create a stronger heel lock and more consistent foot retention, regardless of your instep height. The result is improved stability, better power transfer, and increased confidence when pushing your limits on the slopes.

Fully Customizable Fit

Every skier’s foot is unique, and the S/Pro Alpha 120 is built to adapt. The removable two-piece tongue allows bootfitters to fine-tune the volume around the instep by adding or removing material where needed. Combined with Salomon’s Custom Fit™ 4D Race liner featuring thermoformable Talyn® material, this boot delivers a highly personalized fit for maximum precision and comfort.
