For skiathlon racers, Redster SC9 Carbon combines the best of both worlds: support you need for skating thanks to a carbon cuff – and the flex that classic skiing demands. Sitting at the core of the boot is the Carbon Power Base, a single piece of carbon along the length delivering maximum power transmission and stability you can count on, all with a classic skiing flex. Precision padding in the heel locks it comfortably in position and the one-piece upper construction makes for a striking, stripped back look. When the tracks beckon, tighten the boots in a flash thanks to the special lightweight Race Quicklace system – and ski for hours without losing any hold.
