A lightweight, high performance ski boot designed for hardcore skiers, the X Pro 120 comes in at 2015 grams a boot, which is surprisingly light for so much stiffness. Salomon used their TwinFrame2 shell design, which stiffens the shell where needed while leaving other parts of the shell softer to maximize comfort. Additionally, the X Pro 120 incorporates Salomon's 360Adeg Custom Shell and Cuff which allows for the shell to be heat molded like a liner. This feature allows the boot to fit a wide variety of feet sizes with a variable last of 100mm to 106mm. When you mold the shell in conjunction with the Customfit 3D Race Liner you get a truly custom fit right out of the box. This four buckle boot is designed with the modern skier in mind. It has a modern stance and a 24mm oversized pivot for better power transfer to the ski. Wider skis need this extra torsional power to keep them on edge. If you plan on doing a lot of hiking, the X Pro has replaceable sole pads so that when they wear out you don't have to buy a new boot. This boot will take your ski game to a whole new level.
