The brand-new Rossignol Allspeed Pro 120 Ski Boots focus on customization. Its flex adjustment system—a trifecta of screws located on the spine—allows you to tweak the rating to your liking, between 100 and 120. Additionally, its bi-injected polyurethane liner can be molded to your foot for a precise fit. Rossignol’s Sensor Blade construction, a build using less polyether plastic in the lower shell, sheds bulk without sacrificing stiffness and flex where you need it most.
