A narrow, performance last, with the same Dual Core plastic technology featured in Adults ski boots, the Hero World Cup provides rebound and flex control through the turn. The 70 flex version of the boot will be more appropriate for the skiers out there who don't need the resistance offered by the 90. Similarly, heavier and taller skiers, or skiers with a low range of motion through the ankle joint, should look at the 90.

The thermoformable Dual 3D liner perfectly moulds to the shape of the user's feet and will keep them warm throughout the day.
