The Hero World Cup ZA+ is a full-gas, elite-level race boot for competitive alpine racers. It features a 92+mm last plug shell with our stiffest race flex. The extra-thick walls and race hinged design deliver the most efficient power transmission available in skiing. A neutral, upright stance complements the narrow build to emphasize power and edge control, while the ultra-thin cork-flo lace-up liner deliver facilitates an exact fit and unprecedented precision on snow.
