Atomic Redster S9 Ski Boots 2025

Lighten every stride, feel total control, and unleash your power — that’s the philosophy behind the Atomic Redster S9. Built for performance, this skate cross-country ski boot combines lightweight construction, precision fit, and optimal energy transfer.
The Race Fit, paired with the Prolink Racing Split Sole SK, delivers an ultra-precise and lightweight feel, ensuring excellent contact with the ski for maximum responsiveness. Its Low Cut internal construction, inspired by running shoes, minimizes weight to enhance speed, agility, and freedom of movement.
For powerful acceleration, the Carbon Power Base SK — a one-piece carbon outsole engineered specifically for skating — provides direct and dynamic power transfer. The Carbon Loaded Cuff stabilizes the ankle, improving control and efficiency with every push.
The Quicklace system allows for fast, easy adjustments, even while wearing gloves, while the Sidas insole enhances comfort and foot support during long training sessions or races.
Thanks to the Prolink outsole, the Redster S9 is compatible with all two-rail binding systems, including NNN® and Turnamic®, making it a versatile option for performance setups.
