Dependable performance. Easy entry. Total game changer. The men's Rossignol Vizion 4B 100 HV GW ski boots' revolutionary Step In system features an innovative spoiler and spine mechanism that opens wide for easy entry. Once you're locked in, you get all the on-piste performance you'd expect from a four-buckle boot, thanks to a generative-design shell and precision fit of a pre-shaped liner. Made for intermediate to advanced skiers, these boots deliver reliable performance, medium flex and a high-volume fit for days spent cruising corduroy on every piste.
