With a focus on alpine performance and an easy on and off, the Rossignol Vizion 4B Pro 120 MV GW Ski Boot does a lot to earn a spot in our trunk. This timeless 2-piece, 4-buckle boot boasts an accommodating 100mm last, a powerful 120 flex, and a heel-locking thermo-moldable liner that combine to provide powerful control from peak to parking lot. The big difference with this boot happens in the parking lot: The heel's Step-in Tech switch allows us to slip our foot in without pain no matter how cold.
