The old adage that you can do more on a dialed boot and a 20-year old ski than sloppy boots and the latest-and-greatest boards exists for a reason, and boots like the Salomon X Pro 120 Ski Boot make it easy to understand why. Offering up loads of customization, comfort, and bombproof reliability, the boot comes with a rippable 120 flex and heat-moldable 360 degree Custom Shell. Just imagine what it'll do with those shiny new skis. Salomon constructed the X Pro 120 with its TwinFrame 360-degree heat moldable shell, made of bi-material polyurethane. The shell features fully customizable panels around the ankle, shin, instep, and upper foot, so you can dial in a fit that conforms to the shape of your particular feet without taking drastic measures. Molding the My Custom Fit 3D Race liner is also easy and allows you to significantly improve the fit of the boot. Carve down groomers and dive off into the deep stuff with the security of a customized liner that won't let a heel lift or a forefoot wiggle ruin your line. Even once you've gotten the X Pro molded around your feet, Salomon's Articulated Sensifit design, essentially flexible panels around the instep and shin, means you'll be able to slide the boot on and off without a series of dramatic grunts and sighs every afternoon. With its X Pro line, Salomon managed to build boots that won't leave you in a tough spot when you're counting on them, but that are also comfortable enough to wear all day. Salomon's Oversized Pivot, sitting between the shell and cuff, manages to keep the boot laterally stiff, so you won't end up nose-over-tips when you throw power onto your outside leg to carve a deep set of tracks. Once you duck into the fun stuff, the wide power strap and adjustable Flex Boost screw lets you tighten up the flex to make sure your boots are rock-solid and responsive before you say a prayer and drop in. Just don't forget to lock down the micro-adjustable buckles before you do.
