Features
Inspired by the skate boots worn by Atomic world cup pros, Atomic Redster S9 is an out-and-out racer. The genius of this boot is the Custom Fit: heat the liner with a heater and it molds to your foot for a completely personalized fit in minutes. It also comes with an innovative Carbon 3D Chassis with exceptional torsional rigidity. So all your physical strength is directed into your ski for explosive acceleration. The boot features a Prolink outsole, which gives you an exceptional snow feel (and works with all 2-rail bindings including NNN® and Turnamic®). And the Precision Closure System combines ratchet closure, wrapping lace and dissociated Quicklace for a really precise fit and excellent traction.
- Compatible with all 2-rail bindings on the market
- Carbon Chassis: A 3D chassis made of extra-rigid carbon, for great power transmission.
- Rotative Cuff with Carbon Arms: Extra-rigid carbon works like a joint moving forward, and also provides perfect lateral stability.
- Race Fit: A precise fit for competitive athletes.
- Prolink Race SK: A stiffer outsole for more stability and power transmission when skating.

AI FAQs
AI generated FAQs about the Redster S9 Boot 22/23*
How do I know what size to order?
Choose from the offered UK size options, which include UK 5.5 through UK 11.5. The precise Race Fit and heat-moldable Custom Fit liner are designed for competitive athletes seeking a personalized fit.
Will these boots feel tight at first, or do they need time to break in?
The Atomic Custom Fit liner can be heated and molded to your foot for a completely personalized fit in minutes. This fitting process lets you tailor the liner’s shape before you ski.
Can I adjust how snug these boots fit around my ankle and calf?
The Precision Closure System combines a ratchet closure, wrapping lace, and dissociated Quicklace for a precise fit. These closure elements help you secure the boot closely for competitive skate skiing.
Do these boots have good ankle support, or will my feet roll around?
The Rotative Cuff with Carbon Arms provides lateral stability while moving forward. The extra-rigid Carbon 3D Chassis further supports strong power transmission for skate skiing.
Will these boots work with my current skis and bindings?
These boots are compatible with all 2-rail cross-country ski bindings, including NNN, Prolink, and Turnamic. They are suited to the NNN/Prolink/Turnamic binding system rather than bindings outside the 2-rail system.
Will water and snow get inside these boots when I'm skiing?
A lace cover with a sideways waterproof zip protects the boot’s closure area from water and snow. This feature helps shield the laces during wet or snowy skate-ski conditions.
Are these boots made for beginners, advanced skiers, or somewhere in between?
These are race-focused skate ski boots made for competitive athletes and competitive skate skiing. Their precise Race Fit, carbon chassis, and race outsole suit performance-driven skiing rather than casual use.
How much feedback and control will these boots give me?
The Prolink outsole delivers exceptional snow feel, while the Carbon 3D Chassis provides exceptional torsional rigidity. Together, these features direct your effort into the ski for strong power transmission and explosive acceleration.
Are these boots flexible enough for learning, or too stiff?
These boots use a Skating Flex alongside an extra-rigid Carbon 3D Chassis and carbon cuff arms. They are built for competitive skate skiing and competitive athletes, rather than positioned as a learning boot.
