The Atomic Redster STR F5 is engineered for lighter weight, smaller skiers who need precision and power at the World Cup level. This is the 150-flex boot that World Cup racer Sofia Goggia skis in. A slim 91mm Racing Last was uniquely developed for the perfect balance of flex and control for low-volume feet. The World Cup Race Liner with Ankle Retention System creates a responsive connection to the boot so racers can ski with confidence. The shell’s thin yet strong walls made from temperature-resistant Formula Plastics are designed so that smaller or lighter weight Redster athletes can powerfully flex the boot in all conditions. The Redster Adaptive Fit System Tongue can be repositioned for the perfect fit over the instep and the Redster Racing Sole, which is 5mm thicker than comparable soles, offers excellent power transfer.
