The Exo 2.1 is the standard cup here at Cafè K2 although there is nothing standard about this skate. This house specialty mixes the comfort and quality of the K2 Softboot® with supportive ankle lacing, a stability cuff, 78mm wheels and ABEC 5 bearings. Once you slip them on your feet you will understand how this skate made Cafè K2 what it is today. Skate Type: Fitness Wheels: 78mm 80A Bearing: ABEC 5 Chassis: Exo Composite Liner: Foam
