Atomic Redster STI 90 LC Junior Ski Boots - Red/Black

Designed for juniors looking for performance, the Redster STI 90 LC retains all the DNA of World Cup models, with a 15 mm lower cuff to accommodate shorter legs. Its unisex design and narrow fit make it the ideal choice for young racers looking for both stability and control. Lightweight and perfectly balanced, it allows competitors to perform to their full potential on the course.

Redster STI 90 LC junior ski boots: comfort and racing feel

Although designed for competition, this boot does not compromise on comfort. The Atomic World Cup liner ensures precise contact between the foot and the shell, guaranteeing excellent feel on the snow. The Slim Race Shell structure offers a flex rating of 90, which is more accessible than traditional junior racing models, making it ideal for lighter skiers. The result is a perfect balance between power and maneuverability.

Technologies designed for competition

Every detail of the Redster STI 90 LC has been designed to optimize racing performance:

• The Power Control system allows you to adjust the angle and stiffness to find the perfect setting.
• The double PU shell offers strength and precision, essential on fast courses.
• The non-replaceable racing soles, used in the World Cup, guarantee stability and optimal power transmission.

With these technical features, juniors can experience the same sensations as experienced athletes and gain confidence on the starting line.

Durability and high-level commitment

Built to last season after season, the Atomic Redster STI 90 LC relies on the reliability of the polyurethane (PU) materials used in its shell and cuff. Its controlled weight (1,850 g in size 24/24.5) ensures a good balance between resistance and comfort of use. Designed to meet the demands of alpine competition, it offers young skiers an experience close to that of professionals, while allowing them to progress confidently to the highest level.
