We designed the Maysis to perform like a workhorse and fit like a glove, and its feature-forward design has it ranked as a perennial bestseller. It starts with a heat-moldable liner made of open-cell Intuition (R) 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 our Conda (TM) liner lacing system. Powered by a BOA (R) 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. K2 Maysis Snowboard Boots Mens | Gray | 11 | Christy Sports
