The secret to the award-winning fit is the K2 Conda™ liner lacing system. Powered by a BOA® Fit System dial, this forgiving and adjustable harness is designed to pull the user's heel into the boot's heel pocket. This urethane-based harness hugs your ankle and flexes naturally. Externally, an articulating cuff to reduces distortion when bending the knee, and an integrated Flex Zone calf panel at the top of the cuff helps to keep legs happy all day long. A high-powered BOA® Fit System H4 Coiler closes the shell securely and can be done without removing your gloves. Lastly, to add durability and maintain the boot's flex over the boot's lifetime the Contour was constructed using Endo™ technology. Underfoot, K2 used premium materials to improve damping and grip. The outsole is built using proprietary This Grips!™ dual-rubber compound to provide excellent grip both on and off the snow. This is all set atop a dual-density midsole comprised of a lightweight EVA and proprietary Harshmellow™, designed to dampen vibration on rough terrain, and cushion big landings. Lastly, K2 wrap your feet in a breathable Intuition® Pro Foam 3D liner, fully customizable and heat-moldable to fit the exact shape of your feet, and contains a 95% post-consumer recycled coffee mesh to control foot odor.
