100mm last: A performance width for advanced recreational skiers all the way up to expert level skiers. This is also suitable for skiers with narrower than average feet.
120 Flex Rating: This boot is too stiff for beginners and even most intermediates. At this flex, the skier should be advanced to expert level, comfortable skiing at high speeds anywhere on the mountain.
Tongue Pull: A loop of fabric at the top of the tongue helps in putting on and removing the boots. Pull it forward and to the side and your foot should slide right in.
Macro adjust ladder: The tooth plate opposite the top buckles can be moved in or out for a huge range of adjustment, and to fit narrow to wide lower legs.
Full Thermo Fit Liner: Body heat activates the material in this liner to shape to the skier’s foot faster than a standard liner. The insulation also has heat reflective properties to keep the warm in, and the cold out.
40mm strap: Super wide strap found on high performance boots. The extra width spreads out the force while skiing and reduces the pressure point on the upper shin.
Micro-adjustable aluminum buckles: These aluminum buckles can be moved to adjust for size, so if the default position of the buckle and the teeth is too wide or too narrow, you can move it until it fits.
One Piece Toebox: The solid one piece toebox is integrated into the liner to prevent deformation when putting on or taking off the boot, as well as eliminating any pressure points caused by liner seams.
Diagonal Buckles: Rossignol has patented their diagonal buckle design, which are both easier to clamp down, and pull your foot back into the boot as opposed to just pressing your foot into the footboard.
SensorFit Technology: Rossignol’s Sensor boots are anatomically designed to have direct contact with the foot’s ‘balance receptor points’ (big toe, little toe, heel) to give a comfortable fit as well as greater power that comes from greater balance. Additionally, Sensor fit boots have a seamless, one piece tongue and a cushy instep pocket too, both of which are there to minimize pressure points no matter how tight you lock down your buckles.
