Atomic Redster STI 110 Race Ski Boot 2021



The Atomic Redster STI 110 with the Slim Race Shell is our most flexible race boot for adult skiers – easy to flex with plenty of stability. 


For lightweight skiers seeking a low-volume race boot, there’s no better match than the Atomic Redster STI 110. The Slim Race Shell offers plenty of flex while providing top-notch stability, and it has the same World Cup Liner as the stiffer options in the line-up. The Narrow Fit 93mm last makes this boot the perfect choice for skiers with low-volume feet, letting them lock-in the boot feel and ski with unlimited confidence. For the lightest-weight racers that still want to rip, this boot will hopefully make their podium dreams come true.
