Mondo 18.5 Kid's Lange RSJ 50 All Mountain Ski Boots (Used)

These are used Lange RSJ 50 kids' all-mountain ski boots in Mondo sizes 18 and 18.5, designed for young skiers. The RSJ 50 model features a very soft flex, under 70, which prioritizes comfort and ease of movement—ideal for beginners and early intermediate kids still building their skills. The medium width (99-101mm) ensures a balanced fit that accommodates average foot shapes without being too tight or loose. The boots have a 231mm sole length, standard for this size range, allowing compatibility with most junior bindings. These boots are best suited for younger skiers roughly in the age range of 4 to 7 years old who need a forgiving boot that supports learning on a variety of terrain. The very soft flex reduces fatigue and helps with control at lower speeds, making them appropriate for kids developing confidence on skis in all-mountain and carving conditions.
