Customizable boots have a reputation as being seriously comfortable, and they are. A total custom fit doesn't get as much credit for helping make your skiing better, though, which is exactly what it does just try the Salomon X Max 110 Women's Ski Boot if you need proof. Not only does it boast a fully customizable liner, but the shell itself is made of Salomon's heat moldable 360 Custom Shell material, which can be formed to your foot to provide space where you need it, eliminate it where you don't, and help improve the power and precision of your skiing. The moldable shell is made of bi material polyurethane, and features fully customizable panels around the ankle, shin, instep, and upper foot, so you can dial in a fit that conforms to the funky shapes of your feet without any aggravating punching or grinding. It's also easy to mold the My Custom Fit 3D Race women specific liner, so you can dial down a fully personalized fit that improves your downhill performance while helping to keep your feet locked down and comfortable even in tough terrain. Salomon also designed the X Max with a short cuff to better accommodate women's calves, and included a cuff adjustment screw that can provide some extra volume to better fit ladies with wide lower legs. Crushing the comfort aspect of a boot is undoubtedly a good thing, but prioritizing it over performance isn't really the right call. There are no such worries with the X Max, which uses Salomon's Oversized Pivot the pivot is the spot where the shell and cuff are joined to keep the boot laterally stiff, which is key when you're trying to roll wide powder skis edge to edge. The wide power strap lets you reduce the volume and batten down the hatches when you start skiing more aggressively, and the micro adjustable buckles cinch your foot down into the bootboard for killer control with zero slop.
