The Redster STI 150 LIFTED is the boot of choice for Atomic’s skiers on the World Cup Circuit. It’s like a Formula 1 race car turned into a ski boot – engineered for lightweight, smaller skiers who want to attack the course every chance they get. The Slim Race Shell offers the perfect balance of flex and control. The sole has a 5mm Injected Lift to provide more leverage so you can rail every turn with confidence. The 93mm Narrow Fit last is perfect for low-volume feet, and the World Cup liner creates a responsive connection to the boot so racers can drive their skis as hard as possible. The V3 Tongue System allows you to select the tongue volume that best fits your body, for a dialed interface between your shin and the boot. If you want to go fast from gate to gate to finish, be like Sofia Goggia and grab a pair of Redster STI.
