Weight	Approx. 1940 g per boot (24.5 reference)
Ideal For	Competitive junior racers needing strong support

The Hero World Cup 90 SC is built for aspiring racers who are pushing hard through gates but are not ready for full adult plug flexes. The 97 mm last gives a snug, race-inspired fit that still allows enough circulation and warmth for long training days. Rossignol’s Dual Core polyurethane shell focuses stiffness where it matters while keeping the flex pattern energetic and predictable for clean edge engagement. A dedicated short cuff (SC) design matches shorter legs and helps juniors find a natural, centred stance with better ankle range of motion. Inside, the Racing liner uses dense foam and a power wrap tongue to hold the foot securely, so every movement translates cleanly to the ski.
