The Atomic Redster STR 1 LC is a race-ready boot built specifically for junior athletes, offering a 70 flex and a lower cuff height to accommodate shorter legs. With a 91mm Narrow Racing Last and sizing that goes down to Mondo Point 21, it’s perfectly tuned for younger skiers developing their edge control and power. The PU shell and cuff are paired with Atomic’s STR Wall Thickness for a softer, more forgiving flex that still delivers precise performance. Inside, the World Cup Gold Low liner is tailored to the shell’s low-cuff fit, giving a snug, race-focused feel. The Redster Solid Sole ensures secure binding engagement, making this boot an ideal pick for young racers chasing podiums.
