The Salomon S PRO 120 Men's Ski Boots in Race Blue Acid ski boot available with heat-moldable shells. The S Pro boots feature Salomon’s heat-moldable, “seamless” liners. The S Pro 120 features a heat-moldable PU cuff and boot, and the boot has Salomon’s “Coreframe” fibreglass reinforcements around the midfoot. This tech is designed to increase rigidity without adding much weight and is a part of why Salomon can make the S/Pro boots so light.
The S Proline uses similar construction to their S/Max boots, which are quite light. The S/Max and S/Pro lines are part of a trend we’ve been seeing over the past few seasons — dedicated alpine / inbounds ski boots getting lighter. The new Salomon S Proline takes their new lightweight construction and applies it to a roomier, more comfort-oriented fit.
