The Maysis was designed to perform like a workhorse and fit like a glove and its feature-forward design has it ranked as a perennial bestseller. Its success starts with a heat-moldable liner made of open-cell Intuition foam - allowing the liner to form to the exact shape of your leg ankle and foot for superior fit warmth and comfort. The secret to the award-winning fit is the Conda liner lacing system. Powered by a BOA Fit System dial this forgiving and adjustable harness is designed to pull the users heel into the boots heel pocket. This urethane-based harness hugs your ankle and flexes naturally. Externally designers started with an articulating cuff to reduce distortion when bending the knee and added an abrasion-resistant rubber compound for unrelenting durability. A high-powered BOA Fit System H4 Coiler closes the shell securely and can be done without ever removing your gloves. Lastly to add durability and maintain the boots flex over the boots lifetime the Maysis is designed using Endo technology. Underfoot premium materials 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.
