The V02 Max 90 is K2"s entry into the X-Training category, but there is nothing entry-level about these skates. Designed with the Vortech Ventilation System, this skate uses an intricate pattern of vents, channels and exhaust to minimize moisture in the skate and liner, keeping the overall weight of the skate supremely light. A longer Vortech Frame delivers maximum power transfer and the Vortech Cuff is sculpted to deliver support where you need it without the excess weight. As if that"s not enough, K2"s Quick Lace will have you in and out of your skates in a flash, while 90mm Wheels and ILQ-9 Bearings create a fast and smooth roll.
