The Redster STI 90 LC is a feature-packed race boot designed specifically for lighter junior racers – with a lower cuff to fit shorter legs.

The Redster STI 90 LC is for lighter junior racers, but the only thing junior about this race boot is the cuff height, just a little bit lower for less-developed legs. Memory Fit and World Cup Liner make sure it’s got great foot feel, and the Slim Race Shell makes it easier to flex than normal junior race boots. Power Control lets racers adjust both the forward lean and the precise stiffness of the boot – letting them lock in the feel for tons of confidence on race day. Let junior racers feel like they’re in the big leagues with the Redster STI.
