The Viva Inferno Crush blends two of Tecnica’s lines into one big- mountain dominating boot: the Viva series, which is designed specifically for women, and the Inferno series, which is designed specifically for kicking ass. The low-volume two-piece boot uses a new system that allows you to get your foot in and out easily, which isn’t always the case with high-performance, race-inspired boots. The Viva has a flex of 100, which is stiff for a women’s boot, and thus should be looked at by serious women skiers only.
