Rossignol's low-volume X-ium Men's World Cup Skate Boot is made for high-performance skiing. Designed with a thermo-adjustable fit and carbon fiber exoskeleton, it is made to transfer all of your power to your skis so you'll move faster with less work. The thermo-adjustable fit customizes the volume in the heel pocket. The process fits the boot better and keeps your heel locked down so you won't ever get blisters. The X-ium World Cup Skate Boot flexes across the toes giving you maximum push and glide out of each kick. A double lacing system and ratcheting cuff lock ensures your feet stay locked in place; you won't get any play between the boot and your foot, which could cause blisters and power loss.
