Description & Features
This race ski boot is built for junior racers developing precision, balance, and control. The Rossignol HERO WC 90 SC features an updated World Cup shape with a refined 97mm last that sits closer to the foot, improving power transfer and foot interaction. Dual Core Race construction delivers a progressive, more forgiving flex with consistent rebound, helping this race ski boot feel smooth and predictable through every turn.
The short cuff design supports smaller legs with a more natural stance and better mobility. A reinforced shell and cuff increase torsional rigidity and rear support, so you stay forward and connected to the ski. This race ski boot also includes adjustable flex inserts and race canting, allowing you to fine-tune feel and alignment as skills progress.

FIT & PERFORMANCE TECHNOLOGY
Dual Core Race
A dual-injection process uses multiple materials in the shell and cuff to create progressive flex, consistent rebound, and efficient lateral power transfer. This helps maintain control and stability as speed increases.
Geometric Shape
The refined 97mm last positions the foot closer to the shell with a steeper instep angle, deeper heel pocket, and reduced sole length. This improves precision, power transfer, and foot interaction.
Power Flex Insert
An insert at the cuff hinge strengthens the connection between shell and cuff. Includes a pre-mounted hard carbon insert and a softer PU option to adjust flex based on skier preference and conditions.
Shell & Cuff Structure
Thicker shell walls and a reinforced rear cuff increase torsional rigidity, rear support, and rebound, helping you stay forward and drive the ski effectively.
Race Canting
External canting options (0.5° installed, 1° included) allow precise stance adjustment for improved edge control and responsiveness.
