The NEW VO2 S 100 BOA is the premier skate in our x-training category, and for good reason. 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 BOA is outfitted with the BOA Fit System, giving skaters the ability to easily get in and out of their skates, dial in a precision fit and make on-the-fly adjustments. 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 S 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, youll find the VO2 S BOA atop the x-training mountain.
