Everything you own is custom from your monogrammed bath towels to the toaster that sears your initials into the bread so why ruin your ski vacation by getting boots that aren't tailored specifically to your feet' Salomon's X Pro 100 Ski Boot gives you a fully customizable fit, from the shell to the liner to the buckles, so you can enjoy cush comfort that'll make you feel better and, in turn, ski better. Heat moldable liners are as standard on the mountain as expensive French fries sure enough, the X Pro comes with a My CustomFit 3D Performance heat moldable liner but moldable shells aren't nearly as common yet. Salomon's 360 Custom Shell is leading the moldable charge, though, and the X Pro's ability to be heated up, buckled down, and cooled to give you a totally custom fit is an unbeatable way to dial in the ultimate combination of comfort and performance. While the shell can be easily shaped to fit all the bones and bumps on your feet and ankles, the Twinframe technology and oversized pivot provide stiffness in key zones and easy flex in others, so you can easily put power to your edges and drive wide powder skis without losing any energy in translation. Salomon also designed the X Pro with Articulated Sensifit design, which employs stiffer material in key zones and more flexible material in others, so you can ski hard and still have an easy time putting your boots on and taking them off. Micro adjustrable buckles provide one more way to nail a precise and comfortable fit, and a flex adjustment mechanism located on the shell allows you make slight changes to the feel off the boot to account for energy level, skiing style, snow conditions, and temperature.
