The VO2 90 PRO Inline Skates are ideal for the entry-level cross-training skater who loves skating and looking to go from recreational to that cross-trainer level. The bigger wheels are also accompanied by K2s Vortech Ventilation System, designed to keep feet cool and dry. Our Speed Lacing System makes fine-tuning the fit of the V02 90 a cinch, and its Vo2 cuff and Vo2.2 frame creates the perfect balance of speed, stability, and support. Strap these on and skate away!
