Salomon S/PRO ALPHA Ski Boot

With a 98 mm last, this is considered a performance-fit boot, which is generally narrower than average. If you typically require a high-volume fit, this model might feel too restrictive, though the heat-moldable shell does offer some room for customization.

Salomon uses a thinner plastic profile over the instep area and a strategic buckle placement that allows the shell to open wider than traditional overlap boots. This makes sliding your foot in and out much smoother, especially on cold mornings when plastic is stiffer.

These boots come with premounted Gripwalk soles, which are compatible with Gripwalk-certified bindings and most modern touring bindings. However, they are not compatible with traditional ISO 5355 alpine bindings, so please verify your current binding setup before purchasing.

A 100 flex is a medium-stiff rating, designed for intermediate skiers who want a balance between comfort and responsiveness. It provides enough support to drive power into your skis for carving and control without being so rigid that it becomes fatiguing during a full day on the mountain.

Yes, for the best results, you should have the shell heat-molded by a professional boot fitter. They have the specialized ovens and tools required to expand the shell to match your specific foot shape, ensuring a precise, pressure-free fit.
