While the Redster STI 70 LC is Atomic's most flexible race boot for junior ski racers, the only thing junior about this race boot is the cuff height, specifically sized for younger legs. The Slim Race Shell makes it easier to flex than other junior ski boots. The Redster STI 70 LC has a high-performance World Cup liner that creates a precise interface between shell and foot and works with the V3 Tongue System to totally fine-tune your fit. The V3 Tongue System allows you to select the tongue volume that best fits your body, for a dialed connection between your shin and the boot. This is a boot that’s ready to perform on the race course. Junior racers will have tons of confidence on race day and feel like they’re in the big leagues with the Redster STI 70 LC.
