Lange RSJ 65 Junior Ski Boots

The Lange RSJ 65 Junior Ski Boots are designed for young racers and all-mountain skiers who need a performance-driven boot to support their progression. With an easy-flexing 65 rating and a mono-injection polyurethane shell, the RSJ 65 delivers smooth energy transfer and dependable control without overwhelming developing skiers. Built specifically around Lange’s Junior Fit, this boot addresses smaller calves and foot shapes to provide enhanced comfort, warmth, and performance for skiers ages 12 and under.

Why we like it:

It strikes an excellent balance between support and forgiveness. The RSJ 65 gives junior skiers real performance benefits in a package that remains approachable and comfortable for long days on the hill.

Who it's for:

Intermediate to advanced junior skiers, including young racers, who need a supportive yet manageable flex. Ideal for kids ready to move beyond beginner boots and into something with more precision and control.

Highlights:

The RSJ 65 features a durable polyurethane shell that offers strong rebound, response, and long-term durability. Lange’s Anatomic Junior Fit is tailored specifically for smaller calves and feet, enhancing comfort and control. A four-buckle aluminum closure system ensures secure, even retention and improved durability. Junior GripWalk compatible soles provide better traction and a more natural walking motion, while replaceable toe and heel pieces extend the life of the boot.

Things to consider:

The 65 flex is supportive for junior skiers, but very lightweight or less aggressive children may find it too stiff if they are still early in their development.

Fit & sizing considerations:

These boots are designed around Lange’s Junior Fit and generally run true to size. Most young skiers should select their standard ski boot size, with room for professional fitting adjustments as needed.
