The Salomon Men's S/Max 100 Ski Boots were designed with Salomon's Fast Collective! It's Coreframe construction uses a thinner shell, making S/MAX lighter, more agile, and more sensitive. In addition to the pre-shaped seamless liner its fit is customizable under ten minutes, thanks to the new CUSTOM SHELL HD, which allows you to choose from 3 different positions of the instep buckle for optimum in-step comfort, full customization and personalized foot hold.
