Lange RSJ 50 vibrant blue
The Lange RSJ 50 is the ideal ski boot for young skiers looking to improve their technique while gaining confidence and control on the slopes. Inspired by racing, it combines sporty performance with a very forgiving flex – perfect for progressing step by step.
The PU shell ensures reliable power transmission and a responsive feel, while the anatomically shaped design securely wraps the foot for optimal support. With a 50 flex, the boot is specifically designed for lighter young skiers, offering a comfortable and easy-to-control performance.
The thermoformable liner adapts precisely to the foot shape, providing a comfortable and accurate fit. This creates a natural skiing feel, allowing the boot to act as an extension of the body.
Lightweight aluminum buckles ensure a secure and durable closure while remaining easy to use. The specially developed junior last delivers a precise, race-inspired fit that supports skill progression.
