The Avanti series was designed for the high performance skier looking for a more traditional 4-buckle and overlapping shell system. The Avanti 120 is the stiffest boot of the series, giving you the highest performance in all conditions. Dalbello's Contour 4 Technology focuses on an anatomically correct position for the foot inside the boot. The toes, ankles, heel, and width of the boot are all designed to give you the best fitting boot possible.
