From New Moon:
Elite construction design and materials and racer input on design. A significant amount of xc racers and biathletes have forgone contracts with their ski companies to use these boots.
From the Manufacturer:
A mere second can separate losers from champions. For that winning edge, we designed the new ELITE 3.0 SKATE. Lighter than its predecessors, it offers the best weight to functionality ratio of any boot currently on the market. Built firmly with full carbon cuffing and carbon active edge resting upon an anatomic footbed, this boot holds a tight grip on the foot, supporting it laterally and torsionally even on steeper terrain and through sharp turns.
