The new HERO WORLD CUP SI 110 is a powerful, high-performance boot with an exact, race-inspired fit for expert to advanced skiers. Sensor Inside shells blend World Cup power and precision with Sensor Fit Technology and a 97mm "narrow" fit. The more accommodating forefoot and instep area combine with a strong heel cup, asymmetrical toe box and more articulate ankle area for increased comfort, circulation and warmth.
A patented technology on World Cup boots. The narrow bootboard enables direct contact between the liner and the shell for superior power, control and sensations.
