Atomic Redster STR F4
Compared to the 150 flex race boot, the Atomic Redster STR F4 has a
slightly softer 130 flex for lighter or smaller racers still looking for a boot
that commands control on the race course. The narrow 91mm Racing Last is
perfect for low-volume feet. The World Cup Race Liner creates a responsive
connection to the boot so racers can ski as efficiently as possible, while the
Ankle Retention System with unique lace loops on the liner locks your ankle in
place for the utmost in responsiveness. The boot’s shell is made from a
powerful, but thin Formula Plastics material that’s easier to flex and still
retains high-performance capabilities. The Redster Adaptive Fit System Tongue
can be adjusted for a dialed interface between your shin and the boot, and the
super-strength Redster Racing Sole adds grip and power.
