The Redster Jr 50 ski boot builds technique and confidence – the two key ingredients for young racers. The four buckle design keeps feet secure for maximum power transfer and the cuff and flex alter as sizes go up to fit the skier. The boot comes with a Size Adjuster that adds a half size when you need it. And to help our Atomic racing stars of the future enjoy the slopes for longer, we’ve used 3M™ Thinsulate™ Insulation in our Bronze liner.
