Champions never rest, and the redesigned Nano Carbon Classic improves on its ground-breaking performance with new refinements to flex. The newly-shaped rand and reinforcement focus the flex onto the softshell MemBrain®, letting the boot bend over the length of the ball of foot for precise control and feel of the wax pocket. Its namesake carbon wing heel counter provides torsional stiffness without inhibiting comfort. The PVC-free softshell construction gives the Nano Carbon Classic maximum breathability with water resistance, conforming to the foot shape and keeping your feet comfortable in the most aerobic skiing.
