The VO2 S 90 PRO Inline Skates are ideal for the entry-level cross-training skater who loves skating and looking to go from fitness to that cross-trainer level. The bigger wheels are also accompanied by K2's 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 S frame creates the perfect balance of speed, stability, and support. Strap these on and skate away! *Note: Brake is removable but not compatible with left skate.
