Description & Features

This race ski boot is designed for younger and lighter racers building skills and confidence on snow. The Rossignol HERO WC 70 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 smooth, forgiving flex with consistent rebound, making this race ski boot easier to control while maintaining a strong connection to the ski.

The short cuff design supports smaller legs with a more natural stance and increased range of motion. A reinforced shell and cuff improve torsional rigidity and rear support, helping maintain balance and forward position. This race ski boot also includes adjustable flex inserts and race canting, so fit and performance can be tuned as young racers 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 improves 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 maintain balance and control.

Race Canting

External canting options (0.5° installed, 1° included) allow precise stance adjustment for improved edge control and responsiveness.
