The V02 90 Boa is the ultimate upgrade from the fitness category of skates. Designed with the Vortech Ventilation System, this inline skate uses an intricate pattern of vents, channels and exhaust to minimize moisture in the skate and liner, keeping the overall weight of the skates supremely light. A Boa Closure System takes K2s Original Softboot to a new level of comfort. The Vo2 Cuff provides maximum support while transferring power to the 90mm wheels and ILQ-9 Classic Plus Bearings.
