K2 SKATE VO2 S 90 Pro Inline Skates Black / Blue / Orange, 42.5

The NEW VO2 S 90 is ideal for the entry-level x-training skater looking for a higher-performing model than a fitness category skate.

Leading the way on this innovative design is the VO2 S frame - a single-sided, extruded and machined aluminum frame - designed for the larger wheels that accompany skates in the x-training category.

And speaking of wheels, the VO2 S 90 Pro features four 90mm wheels with premium ILQ-9 S Plus bearings for a smooth, high-speed training experience.

Adding to the comfort of the Original SoftBoot® is the integrated Vortech Ventilation System, a 3-part system for keeping feet cool and dry on intense training sessions by channeling air through the base, footbed and upper.

With the VO2 cuff providing support, this skate is the perfect balance of speed, stability and comfort.
