100 Flex Rating: This boot is pretty stiff, but not insanely stiff. A boot of this level is pretty good for upper-intermediate to expert level weekend warrior that is looking for something stiff enough to provide high-end response, while being wearable for an entire day of skiing.
Target Skier: Advanced to Expert: These boots are stiff enough and performance oriented enough, that we would recommend them to advanced skiers who will be aggressively skiing the whole mountain. Beginners should look elsewhere!
98mm last: Forefoot width of 98mm offers an expertly performing low-volume fit. Boots of this last width can run the gamut from very tight fitting to reasonably comfortable, but they will all fit much much tighter than a rental or intermediate boot.
Atomic ASY Pro Liner: The densest and highest rebound of Atomic's liners, the asymmetrical liner has less padding on the inside of the foot, where you need a sense of feel, and more padding on the outside of the foot, where you need comfort. This liner has a plastic wrap around the upper for even more response, and it also helps the liner keeps its shape over the lifetime of the boot.
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 (SuperMacro): 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.
Shockilla Insert: A 10mm foam insert sits under the heel, between the liner and the shell (without raising the heel) to give greater comfort while skiing over bumpy and icy terrain. It also cushions landings for the skiers that are jumping higher than they should be.
Recco reflector: The Recco reflector system is a location device built into the back of the boot. This allows ski patrol a much greater chance of finding you if you get stuck in the well of a tree or buried in an avalanche. Its not as good as wearing an avalanche beacon, but its the next best thing.
Double Canting: Two adjustment bolts, one each side of the ankle, allow for maximum adjustment for leg/knee alignment problems. The canting helps the skis stay flat on the ground while you are still bow-legged or knock-kneed.
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.
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.
Micro-Adjustable Carabiner Buckles: These buckles are extra strong and curved so you won't break them regardless of what kind of force you're putting on 'em. And the micro-adjustability means you get an easy lockdown every time.
Ridge Walker Sole: Extra grippy sole gives the skier maximum traction for boot packing hikes.
