The Atomic Redster S7 is inspired by our top pro-athlete boots. Fast, stable and super comfortable, you’ll be amazed at how they feel. The Prolink Racing SK outsole and External 3D Heel Counter ramp up the power transmission while your foot stays perfectly aligned thanks to the Carbon Loaded Cuff. When you’re skiing long distances you can’t compromise on comfort, which is why we’ve integrated a high-cut inner boot construction – as well as a snug Sport Fit designed for athletic skiers. With the Quicklace lacing system and central zip on the lace cover, boot adjustment is easy. And thanks to the Prolink outsole, this boot works with all 2-rail bindings including NNN® and Turnamic®.
