K2 VO2 S 100 BOA
Athletes demand a lot from themselves and expect their gear to be able to keep up. The VO2 S 100 BOA® is the premier skate in our x-training category, and for good reason. Updated with a new look for this season and loaded with the tech and functional features demanded by x-training athletes, these skates bring variety, speed and performance to your training plan. The VO2 S 100 BOA® is outfitted with the BOA® Fit System, delivering a micro-adjustable, precision fit, engineered & guaranteed to perform in the toughest conditions. The x-training athlete is sure to appreciate the stiff, single-sided VO2 S Frame, which provides a fast and responsive skating experience while simultaneously absorbing road vibration. Four massive 100mm wheels with ILQ-9 Classic Plus Bearings bring the smooth, high-speed roll expected of top-tier x-training skates. The 3-part Vortex Ventilation System keeps feet cool and dry on those long training skates by channeling air through the base, footbed and upper. With this plethora of skate tech paired with an updated, eye-grabbing look that screams speed, you’ll find the VO2 S BOA® atop the x-training mountain. *Note: Brake is removable but not compatible with left skate.
