The Rossignol VIZION 4B 120 HV GW is a men’s on-piste, performance-oriented ski boot built around a true “easy entry + full alpine performance” concept. Its Step In overlap construction opens wide at the back using an innovative spoiler and spine system, delivering slipper-like entry and exit without sacrificing locked-in support on the descent. A 102 mm HV last provides a more forgiving, high-volume fit for wider feet and/or higher insteps, while a 120 flex targets confident skiers who want precise power transfer and strong downhill control.

Key benefits
- Step In easy entry: wide rear opening for fast, hands-free style on/off
- Locked-in downhill performance: Spine Link Mechanism secures the Steel Spine in a traditional ski position
- Bi-Injected Spoiler: rigid PU for support and energy transfer + soft rubber sides for a tight seal
- Easy-Open cuff: Double Buckle on the lower cuff quickly unlocks the spoiler for smooth entry/exit
- Dual Core shell: targeted power transmission and shell wrapping for livelier response and control
- True Form Step-In Liner: custom-like feel with features that allow wide access while keeping aggressive-skiing support
- Thinsulate™ Stretch: lightweight warmth in cold/damp conditions plus added elasticity for better support
- Seamless Toe Box: reduced pressure points and up to 20% less heat loss at the toe
- GripWalk® soles: more natural walking motion and increased traction off snow
