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.
