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.

90/100 Flex Rating: This boot has an adjustable flex, which can be set as stiff as 100 and as soft as 90. 90-100 flex boots are best for upper intermediate to advanced skiers, or even experts who are more concerned with cruising comfort.

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.

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.

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.

HeatFit liner with anatomical footbed: This liner will adapt to the shape of your feet and lower leg, just by wearing them. The self molding inserts will make the boot more comfortable the more you wear them. The anatomical footbed has additional support in the heel and arch, and has a solid, yet comfortable feel while skiing.

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.

Tri-Injected Energy Frame Shell: Most ski boots are Bi-Injected into the mold to create two different densities of plastic. Head went ahead and did one better, tri-injection molding. This means there are three levels of plastic density instead of two, meaning the transition from the stiff/dense sole of the boot to the lighter upper-cuff of the boot is more fluid. This in turn makes your skiing smoother and the boot has a more predictable flex throughout all parts of the boot.
