The Atomic Redster STR 1 LC is Atomic’s most flexible race boot for junior racers, with a 70 flex and a lower cuff height sized for shorter legs. The 91mm Narrow Racing Last and sizing down to a Mondo Point 21, with appropriate liner construction, makes this boot custom designed for younger athletes. A pliable polyurethane (PU) plastic shell and cuff material, paired with thin yet powerful STR Wall Thickness, are meant to provide an easy-to-handle progressive flex that delivers outstanding ski performance. The World Cup Gold Low Liner is a supple one-piece liner built specifically for this low-cuff shell. This is a boot that’s ready to perform on race day. Depending on foot shape and compression preferences, junior racers considering this boot may also want to try on the Atomic Redster TX LC, a similarly constructed boot that comes in several flex options. Redster Solid Sole adds precise interface with alpine bindings.
