With the Atomic Redster S9 Carbon BOA, you get a high-performance skating cross-country boot for experienced and ambitious skiers who want maximum precision, strong power transfer and a uncompromisingly close race fit. Developed together with World Cup athletes, this top boot in the Redster collection is designed for improved heel hold, increased stiffness, reduced weight and an exceptionally precise closure system.

The Carbon Power Base SK is made from a single piece of carbon and provides direct power transmission, strong stability and efficient acceleration with every push-off thanks to its specific skating flex. Forged Carbon in the powerbase and cuff increases torsional stiffness and improves the stability-to-weight ratio, while the precise Race Fit wraps the foot closely for race-focused performance.

The Dual BOA® Fit System allows zonal fine adjustment through two BOA® dials – even while skiing and without opening the gaiter. Combined with Layerlock, the inner and outer boot are secured at the same time, holding the foot firmly and guiding it with high precision. Additional padding in the heel area improves hold during powerful skating movements.

The low-cut construction saves weight and supports a direct, agile stride feel. The central zipper cover helps protect against snow and moisture, while the forged-carbon-reinforced cuff stabilises the ankle and keeps the foot positioned cleanly over the ski. This gives the Atomic Redster S9 Carbon BOA maximum control, efficient forward drive and true race performance for training and competition.
