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.
80 Flex Index: This boot has a flex rating of 80, which is moving out of the softer-entry level boots and into the stiffer more advanced ski boots. A boot of this flex is appropriate for a wide range of skiers, from lower intermediates looking to improve to expert skiers who want a more casual flex.
PU Shell: Poly Urethane shell (plastic) that resists stretching and is durable for long life.
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.
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.
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.
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.
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.
