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.
