Wait, a powerful 4 buckle overlap boot from Dalbello? Actually, they've made them for years, but they were mostly on the feet of sponsored World Cup athletes. Now the Dalbello DS 90 W Ski Boots are available to the public, and skiing is believing. A performance average last with a 99 mm forefoot, with a heat moldable liner and shell, the DS 90 can accommodate a wide variety of average volume feet.
