S/Lab Classic: An extremely high-performance competition shoe, precisely tailored to the needs of young classic runners.
The foot morphology of young runners was taken into account when developing this shoe. The Classic Flex was also adapted to their weight and running technique. The adjustable heel strap, separate lacing, and Second Skin construction of the S/Lab Classic cross-country ski boot provide plenty of precision and optimal push-off, and the Thinsulate lining with 78% recycled content is also environmentally friendly.
