The Atomic Redster JR 4 is the perfect ski boot for sporty juniors hoping to emulate Marcel Hirscher on the slopes. And one thing Marcel would tell you is that skiing’s a lot more fun when you’re warm. That’s why we’ve added full-on 3M™ Thinsulate™ Insulation to the new comfortable Bronze liner – to keep your feet warm and responsive all day. But what makes these ski boots extra special is they’re not just scaled down versions of the larger ones – the design of the cuff and flex alter as sizes go up to fit the skier. So whatever stage you’re at, it’s easier to learn, easier to progress and easier to have fun.
