The K2 Skate Men's F.I.T. X PRO Inline Skates features K2's Fitness Hi-Lo technology that utilizes a wheel configuration of two 80mm wheels in the front and two 84mm wheels in the rear. This design allows for an agile, maneuverable skate that is stable at speed and low to the ground. K2's Speed Lacing System, combined with the K2 Original Softboot, creates a slipper-like fit and the attention to detail in our skate uppers are sure to turn heads.
