Madshus Redline Skate X - The future of skating is here with our boundary-pushing Redline Skate X boot. The Redline Skate X boot and Rottefella SkateX binding system feature a new connection point that is placed further under the foot for a more powerful and stable stride. This new rotation point is optimized for stability, power and efficiency as extra energy can be precisely transferred through the leg and foot into the snow. The boot also features our new RED Carbon Chassis with a lower, wider base for improved stability, power transfer and control. The new Madshus Pro Ripstop upper and Race Wrap 2.0 liner construction are designed for a comfortable fit and precise connection to the ski. The Redline Skate X boot and Rottefella SkateX binding system fit both the NIS 1.0 and NIS 3.0 plates. Welcome to the future of skating.
