Introducing the Redline

The next evolution in technical, high-performance marathon skates


In our quest to develop a premium marathon skate for the dedicated competitor we knew it had to be light, strong and above all, fast. That’s why we teamed up with Madshus, the celebrated Nordic ski brand known for producing championship-caliber boots for world-class athletes. The result of these efforts is nothing short of extraordinary…

The Redline is available in a four-wheel 110mm model and a three-wheel 125mm model, both featuring a brand new anatomical and supportive chassis.

Finally, the Redline features our Flash Disc wheels – ultra high energy urethane with aerodynamic disc hubs you have to see, feel and hear to believe.

Lace up the Redline and claim your spot on the podium.
