30mm Power Strap: A velcro strap, 30mm in height, acts as an extra buckle to keep the top of the boot together. The 30mm straps are good for recreational skiers or junior racers.

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.

Extended Lever Buckles: Longer than normal buckles give more leverage power to the skier so he/she can close the boot if a tight fit is desired. Its physics, man!

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.

Micro-adjustable alloy buckles: These alloy 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.

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.

Adjustable rear spoiler: With a quick adjustment, the height at the top rear of the boot can be raised or lowered. If you are taller than average for your boot size, or if you just want the extra support at the back of the leg, you can adjust the spoiler up about 1cm from standard. This will also pitch you forward slightly into a more aggressive stance.

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.

70 Flex Index: This boot has a flex rating of 70, which is best suited for beginner to intermediate skiers. Softer boots will be more comfortable, but won't offer enough stability at higher speeds. Stiffer than 70 will give that stability, but start to get a little less comfortable.
