The Salomon S/Max 130 is the perfect option for aggressive, expert level skiers with a narrow medium forefoot and standard calf volume. Custom Shell HD uses a thinner wall construction for better overall feel and energy transfer into the boot. Bring the boot into a qualified ski shop and put the Custom Shell HD to work for enhanced customization. Coreframe is an insert that enhances overall power transmission and delivers direct energy into the ski. Edging gets easier with Sense Amplifier that lets you feel more controlled while getting the ski on edge. My Custom Fit 3D Seamless Race Liner anatomically fit to your foot for wall day comfort on the mountain and can be heat molded to your feet after taking them into a qualified ski shop. The 45mm Sense Claw Strap allows you to tighten the cuff even more for a little more stiffness in the boots for those guys who like to charge down the mountain. Flex Adjusters allow you to smooth out or boost your flex depending on snow conditions. Take on any all mountain challenge that's thrown at you with the Salomon S/Max 130.
