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.
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.
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!
i-flex insert: A flexible plastic under the middle of the foot to allow the boot to flex as the ski flexes under pressure. This helps smooth out turns and returns energy back to the ski to help rebound into the next turn.
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.
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.
Height adjustable spoiler: A quick adjustment via velcro raises the rear top of the boot to give more support on the back of the leg, or when lowered, gives a little more room and comfort for the skier.
35mm strap: Wider than average strap at the top of the boot to help keep the boot together and to give good performance while skiing.
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.
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.
Edge 7000 Buckles: The Edge 7000 buckles are highly durable yet lightweight curved buckles with wide levers for easier opening and closing of the buckles. Each of these buckles is micro-adjustable, and the ladder of the top buckle adjusts to different sizes on the fly, without needing to remove the rivet.
Atomic Hawx boots:The Hawx (pronounced 'hawks') series of boots are a little narrower than average, at 100mm, to give firm snow and all mountain skiers the support necessary to maintain control through ice and variable snow types. An insert under the middle of the foot actually lets the boot flex through a turn to help eliminate or reduce the dead/flat spot of the ski. The same feature gives spring back to the bindings to increase rebound to start the next turn. The Hawx series gives skiers that love to carve an advantage on firm snow as they maintain better edge hold through a turn.
