Nordic skating skis: The Sporten SET SUPER SKATE + PERFORMANCE SKATE are quality skis, and they are designed for sporty cross-country skiers. You almost don't know it's there, so it's natural. You can focus on yourself and the trail. The 3D shape makes the design unique. The core is made from a combination of exotic woods that reduces their weight greatly. Their speed is provided by the high-quality graphite base that has a special structure.
