Designed in collaboration with Salomon's Fast Collective, S/MAX 130 CARBON boots are a radical new way of building boots. Coreframe construction uses a thinner shell with an internal frame reinforecment, making S/MAX lighter, more agile, and more sensitive than anything out there. You'll feel your edges and terrain variations like never before. And the fit is completely customizable, with a pre-shaped seamless liner and new CUSTOM SHELL HD molding process in just ten minutes.
