ATOMIC REDSTER STR 2 LC Ski Boots
The Atomic Redster STR 2 LC is a feature-packed race boot designed specifically for lighter or junior racers, with a lower cuff that better accommodates shorter legs. While the cuff height is junior-oriented, the rest of the boot is built with the same race-focused approach found in Atomic’s top-level Redster boots.
A slim 91 mm Racing Last and sizing down to a true Mondo Point 21 provide a secure, precise fit for smaller and lower-volume feet. The thin but powerful STR Wall Thickness works with a 90 flex to give lighter athletes enough support and control while still allowing them to flex the boot effectively.
The World Cup Gold Low Liner uses soft internal foam for a cushioned fit and includes cuff lacing to improve responsiveness and skiing precision. The Race Chassis reinforces the lower shell for increased stability, power transmission and edge grip, while Podium Geometry places the skier in an athletic race stance.
Atomic’s Memory Fit technology allows the shell and cuff to be heat-molded to the skier’s leg and foot shape. A 15 mm lower cuff across all sizes, Redster Solid Sole and Alpine ISO 5355 compatibility complete a race-focused package for progressing junior and lightweight racers.
