Ski boots Atomic Redster STR 2 LC Red Tension/Black – 2025/26

Although the Atomic Redster STR 2 LC model is designed for lighter or younger racers, the only feature specific to juniors is the height of the upper, which is slightly lower to accommodate shorter legs. Everything else is on par with Atomic's top-of-the-line World Cup boots. The Atomic World Cup Gold Low liner is made of soft inner foam for cushioning, and the upper lacing improves responsiveness and precision when skiing. The narrow, snug 91 mm Narrow Racing Last and sizes down to Mondo Point 21 mean that even smaller and shorter feet can enjoy stability and readiness to ski. The thin but strong STR shell and flex index of 90 allow smaller athletes to flex the boot without losing power and control. Depending on foot shape and pressure tolerance, young racers who like this boot may also consider the Redster TX LC, which is available in several flex options. The Redster Solid Sole works seamlessly with alpine bindings.
