2025 Atomic Redster STI 90 LC Ski Boot

Description & Features

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. World Cup Liner makes sure it’s got great foot feel, and the Slim Race Shell makes it easier to flex than regular junior race boots. Power Control lets racers adjust both the forward lean and the precise stiffness of the boot – allowing them to 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.

V3 TONGUE SYSTEM

Customizable V3 Tongue System allows you to select the ideal tongue thickness to suit your needs. Choose between a Low Volume (LV) fit, Medium Volume (MV) fit and High Volume (HV) fit for the ultimate interface between shin and liner.
