Comfort has never been ski boots' claim to fame they tend to be a lot more like torture devices than cushy slippers but Salomon's figured out that it's really hard to ski well when your feet feel like they're dying. Salomon started thinking of comfort as a part of performance, not something that's antithetical to it. In the easy going intermediate friendly X Pro X90 Men's Ski Boot, the comfort takes the form of a roomy 100mm wide last, a heat moldable and cushy My CustomFit 3D liner, and Articulated Sensifit design, which places a highly flexible panel at the overlap, so its easy to get the boot on and off without having to grit your teeth and breathe like you're an Olympic weightlifter. The boot will take care of your feet, but a good boot still needs to be stiff enough that it can actually be skied. Salomon obliged by giving the X Pro a moderate 90 flex, which is tough enough to be pushed down creamy groomers but doesn't demand intense input, and it's famous Twinframe construction, which maps softer and stiffer material in key areas, balancing responsiveness, snugness, and comfort. It also joined the shell and cuff of the X Pro with a 24mm oversized pivot to ensure a solid and precise connection between the two, and finished the boot off with four micro adjustable aluminum buckles for fit control, a flex adjuster to account for different snow conditions and skiing styles, and a hook and loop power strap to cinch everything down for a responsive but shin bang free ride.
