Rossignol Men’s Vizion 4B Pro 100 MV GW Ski Boots 2026

Step into performance without the struggle. The Rossignol Vizion 4B Pro 100 MV GW brings a totally reimagined Step In shell design to a true on-piste/all-mountain boot, giving intermediate to advanced skiers easy entry, real alpine power, and all-day comfort in a 100 mm medium-volume fit.

What Makes It Work: Step In, Lock In, Charge

• Revolutionary Step In Shell: A ground-breaking overlap shell and spoiler/spine mechanism open wide at the back for effortless entry and exit, then lock down for full alpine performance once you’re buckled.
• Dual Core Polyether Shell: Dual-density construction reinforces key power zones while keeping weight in check, so every movement translates cleanly to your skis.
• Medium 100 Flex: A 100 flex index hits the sweet spot for strong intermediate to solid advanced skiers—supportive at speed but still progressive and comfortable through the ankles.
• Custom Liner with Thinsulate® Stretch: A pre-shaped, full-custom liner wraps the foot securely and uses forefoot Thinsulate® Stretch and a seamless toe box for warmth, comfort, and reduced pressure points.
• GripWalk® Soles: Pre-mounted GripWalk soles add a rockered, rubberized platform for better traction and a more natural walking motion around the parking lot, lodge, and village.

Fit, Feel & Intended Terrain

Built around a 100 mm medium-volume last, the Vizion 4B Pro 100 MV GW targets skiers with average-width feet who want a secure yet comfortable fit. On snow, it feels smooth, damp, and confidence-inspiring—perfect for carving groomers, ripping afternoon chop, and exploring the whole piste without fighting your boots. If you’ve outgrown rental gear or softer entry-level boots and want real performance without giving up comfort or ease of use, this boot is right in the zone.
