Mondo 21 & 21.5 Unisex Lange RSJ 65 Racing Ski Boots (Used)

The Lange RSJ 65 racing ski boots in Mondo sizes 21 and 21.5 are designed for young skiers who require a soft flex boot that supports developing technique without compromising comfort. With a flex rating under 70, these boots provide easy bending, making them suitable for beginners or lighter racers focusing on control and form. Their unisex fit accommodates a range of foot shapes common at smaller sizes, and the racing-style construction offers responsiveness appropriate for entry-level race training. This listing is for a used pair, reflecting standard wear consistent with functional ski boots. These boots are well suited for junior racers aged roughly 7 to 10 who are transitioning from recreational skiing to more structured race environments. The softer flex aids in maintaining balance and reducing fatigue during longer sessions on the course. Buyers should consider these if they need a reliable, forgiving racing boot in a smaller size to help build foundational skills before moving to stiffer, more performance-oriented models.
