ATOMIC ski boots Redster STI 90 LC

Redster STI is a world cup level ski boot with a big following due to Slim Race Shell construction. It´s a thinner shell so it´s easier to flex and control, but still super stable. This delivers a high performance race boot that´s perfect for lighter skiers.

Atomic Redster STI 90 LC - 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 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.
