The K2 Renin blends a classic silhouette, technology that matters, and a fit that wins time and time again. Our Mobility Conda™ Boa® is wrapped around an Intuition® Pro Foam 3D Liner and works in harmony with a softer Flex Zone upper. K2 added a Vibram® RollSole to give the Renin increased lateral mobility to help channel surf style vibes and ensure good times.
