Designed for lighter junior racers, the Atomic Redster STI 90 LC delivers a true racing feel with just one junior-specific feature: a slightly lower cuff to better fit shorter legs. Its Atomic World Cup liner provides exceptional feedback and a precise link between the liner and the shell. The Slim Race Shell construction ensures a more forgiving flex compared to standard junior race boots. With the Power Control system, athletes can fine-tune both forward lean and stiffness, customizing the fit to boost confidence on race day. The Redster STI 90 LC gives young skiers the sensation of competing with world-class gear.
