Lange RSJ 50 Ski Boots

Easy flex, junior comfort.
The Lange RSJ 50 Ski Boots are built for the youngest skiers (ages 8 and under) who are ready to progress with confidence. With a soft, forgiving 50 flex and junior-specific design, the RSJ 50 offers the right balance of support, warmth, and comfort for small skiers learning to ski all-mountain terrain or starting in junior race programs.

A junior mono-injection shell, cozy Control Fit liner, and simplified three-buckle closure make the RSJ 50 easy to use while providing the secure fit and performance needed for safe, fun days on snow. Specifically designed to fit shorter lower legs, smaller calves, and narrower foot shapes, this boot gives kids the comfort and control they need to progress quickly.
