This totally unique shell construction has thinner walls meaning better flex and control for lighter racers.
Forward lean can be quickly adjusted as well as the flex index by +/- 10 flex points.
This highly anatomical narrow last (93mm in size 26/26.5) is the lowest volume fit used by our World Cup athletes and the choice of Downhill Globe winner Sofia Goggia.
The Atomic Redster STI 150 LIFTED is the boot of choice for our skiers on the World Cup Circuit. It’s like a Formula 1 race car turned into a ski boot – engineered for light but aggressive skiers with a Slim Race Shell that offers more flex while retaining stability. The sole has a 5mm Injected Lift to provide more leverage while initiating turns – have your bootfitter grind it down to meet alpine-normed boot standards. The 93mm Narrow Fit last is perfect for low-volume feet, and the World Cup Liner with Memory Fit helps racers achieve the perfect fit to drive their skis as hard as they can. If you want to go fast from gate to gate to finish, be like Sofia Goggia and grab a Redster STI.
