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.
102mm last: Slightly wider than average to give a great fit for most skiers. This last was designed to fit pretty much everyone, but really wide feet, or the opposite, should look for different lasts more appropriate for their foot types.
Micro-adjustable alloy buckles: These alloy buckles can be twisted to adjust for size, so if the default position of the buckle and the teeth is too wide or too narrow, you can twist the buckle like a screw until it fits just right.
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.
Single Canting: One adjustment bolt on the outside of the ankle helps compensate for bow-legs or knock-knees. This tilts the cuff of the boot left or right while keeping the base of the skis flat on the snow.
Replaceable Toe and Heel Pads: This is a must-have for skiers that don't live in ski in/ski out condos. When your ski tech tells you that you have to buy new boots because the soles are worn down too much, just laugh at him and tell him to order you a new set of sole plates.
45mm 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.
Biovent Liner: This liner is highly breathable thanks to multiple layers of foam and wicking materials. Dry feet lead to warm feet, so these liners are warmer than standard liners.
Progressive Flex Cuff: Salomon's Progressive Flex Cuff Design provides a more ergonomically shaped shell in the calf area.
My Custom Fit Liner: Extra layers of heat moldable foam in sensitive feet areas to increase comfort and improve fit.
