Step into a revolution — the easy entry and high performance revolution of our innovative Step In design. Made for skiers looking for a medium volume fit and medium flex, the Rossignol Vizion 4B Pro 120 MV ski boots feature a ground-breaking overlap shell design that opens wide in the back for unparalleled slip-on ease thanks to an innovative spoiler and spine mechanism. The system creates wide articulation at the cuff and complete locked-in support for precise power transfer and full downhill performance with unmatched ease of use. Just slip in, buckle up and ski.

Medium-Volume Fit
Medium-Volume fit features a 100mm last for a performance feel that balances comfort and control

Slip-On Ease, Full Alpine Performance
Step In technology is a revolutionary new overlap boot design that delivers the highest levels of ski performance with first-of-its-kind, hands-free entry and exit

Locked-In Performance
Our Spine Link Mechanism is the magic that makes Vizion the easiest entry and exit alpine boots on the market. When locked, the mechanism holds the Steel Spine in a traditional ski position. When released, it allows the boot to open wide for slipper-like entry and exit.

Full Support, Easy Entry
The Bi-Injected Spoiler features rigid PU material for the support and energy transmission of a traditional alpine boot, while its soft rubber sides wrap to form a tight seal. Extended backwards articulation makes for incredibly easy boot entry and exit.

Easy-Open Cuff
A unique Double Buckle on the lower cuff effortlessly unlocks and releases the spoiler for smooth, slipper-like entry and exit

Better Skiability, Better Fit
Dual Core technology provides targeted power transmission and shell wrapping, resulting in livelier rebound, response and control

Our True Form Step-In Liner offers the fit and feel of a traditional custom fit alpine liner with key features that allow wide access for easy entry and exit while retaining the support needed for aggressive skiing
