ROSSIGNOL Vizion 4B Pro 120 MV GW

The ROSSIGNOL Vizion 4B Pro 120 MV GW is a high-performance men’s/unisex all-mountain ski boot that combines strong downhill performance with exceptionally easy entry and exit. At the heart of the concept is innovative Step In Technology, which allows the rear section of the boot to open wide for significantly easier entry without sacrificing the support required for performance-oriented skiing.

The model combines a 120 flex with a 100 mm Medium Volume last, making it suitable for experienced, sporty skiers who want a precise and sufficiently stiff boot without the narrow fit of a race-oriented shell. Its polyether shell incorporates DUAL CORE VIZION, Generative Design Grid and a Steel Spine reinforcement. A specific bi-injected spoiler and rear construction allow the boot to open widely for entry and then close securely to create the support needed for skiing.

Comfort is enhanced by a FULL CUSTOM PRE-SHAPED LINER with a SEAMLESS TOEBOX and THINSULATE insulation. Pre-mounted GRIPWALK® soles make walking without skis more practical, while their rubber tread and articulated toe support more natural movement and improved contact with the ground. The Vizion 4B Pro 120 MV GW is therefore an interesting solution for skiers who do not want to choose between easy entry, comfort and performance.

Who are these ski boots for?

The ROSSIGNOL Vizion 4B Pro 120 MV GW is primarily designed for sporty skiers who want the strong support of a 120 flex while also appreciating a more comfortable Medium Volume fit and significantly easier entry than conventional performance ski boots.

The model is particularly suitable for skiers who:

  • ski at a performance-oriented level and want strong support for dynamic skiing
  • are looking for a 120 flex without moving to a narrow race-oriented construction
  • prefer a Medium Volume shell with a 100 mm last
  • want to make putting on and taking off their ski boots significantly easier
  • demand precise power transmission while skiing
  • appreciate a pre-shaped liner with a seamless toe area
  • want the thermal insulation of Thinsulate
  • value the practicality of pre-mounted GripWalk soles
  • are looking for performance all-mountain boots for full days on the mountain

The combination of a 100 mm last and 120 flex gives the boot a sporty yet more versatile character than narrow Low Volume models. Correct sizing and a shell shape that matches the individual foot remain essential.

How do the boots perform on the slopes?

The Vizion 4B Pro 120 MV GW is engineered so that its unusual easy-entry system does not compromise the stiffness and support required for downhill performance. Once the boot is closed, the rear construction works together with the bi-injected spoiler, Steel Spine reinforcement and cuff to create a supportive structure focused on efficient power transmission.

The 120 flex provides enough support for dynamic ski control, active pressure through the turn and performance-oriented skiing at higher speeds. At the same time, the 100 mm Medium Volume construction provides a balance between precise foot retention and a more versatile fit.

The result is not a soft comfort boot focused solely on ease of use. The Vizion 4B Pro 120 MV GW remains a genuine performance-oriented ski boot, with easier entry serving as one of its key construction advantages rather than a substitute for downhill performance.

How to understand the parameters

Flex 120

The exact 120 flex index places the Vizion 4B Pro 120 MV GW among stiff performance ski boots. This level of flex provides substantial support when loading the cuff and is well suited to more experienced skiers who ski actively and know how to work with a stiffer boot.

Compared with softer recreational models, a 120 flex allows more precise pressure control and provides stronger support during dynamic skiing. At the same time, it requires an appropriate level of technique and strength.

Flex indices are not fully standardized between manufacturers, so a value of 120 should always be considered together with the skier’s weight, strength, technical ability and skiing style.

100 mm last – Medium Volume

The 100 mm last represents a Medium Volume construction. Compared with narrow performance boots around 97–98 mm, it provides more internal space while retaining a fit suitable for precise and sporty ski control.

For many skiers, 100 mm represents a versatile balance between comfort and control. The number itself, however, is not the only deciding factor – the overall shape of the foot, instep, heel and internal boot geometry are equally important.

Technologies

BI-INJECTED HIGHBACK

BI-INJECTED HIGHBACK is an important part of the Vizion’s distinctive rear construction. The bi-injected spoiler works with the opening mechanism to allow significantly easier entry while providing the necessary support for performance skiing once the boot is closed.

The ability to combine a wide opening during entry with a supportive rear structure while skiing is one of the fundamental principles behind the Vizion design.

DOUBLE BUCKLE

DOUBLE BUCKLE is part of the closure system used on the Vizion 4B Pro 120 MV GW. It is designed to work with the specific Step In construction and help secure the boot once the foot is inside.

The system is therefore not simply an isolated closure element, but part of the overall concept that combines easy entry with the foot retention and support required while skiing.

DUAL CORE VIZION

DUAL CORE VIZION works with the shell construction to balance the characteristics required for easier boot handling with the stiffness and response expected from a performance-oriented ski boot.

Together with the other structural elements, it helps create a boot that can open as required for easier entry while still providing the support appropriate for its performance focus once skiing.

Generative Design Grid

Generative Design Grid focuses on optimizing the shell construction. Its structure is designed to use material efficiently in areas where it is important for strength, support and power transmission.

The result is a construction aimed at delivering the required stiffness and response without making the entire shell unnecessarily bulky.

GRIPWALK®

The pre-mounted GRIPWALK® soles improve practicality when moving without skis. Their profiled construction with rubber tread and articulated toe supports a more natural walking motion and better contact with the ground than a conventional flat alpine sole.

Because the boots are equipped with GripWalk soles, they must be used with GripWalk-compatible ski bindings.

SEAMLESS TOE BOX

SEAMLESS TOE BOX technology focuses on the toe area of the liner. Its seamless construction reduces seams in this sensitive part of the boot and contributes to a cleaner, more comfortable environment around the toes.

In a performance boot designed for full-day use, this is an important detail, as poorly positioned seams or pressure points around the toes can significantly reduce comfort.

Thinsulate Insulation

Thinsulate Insulation is incorporated into the liner and focuses on thermal comfort. The insulating layer helps reduce heat loss and supports a more comfortable environment around the foot during skiing.

This is particularly useful in a performance boot that combines a more precise fit with the aim of providing comfort throughout a full day on the mountain.

Step In Technology

Step In Technology is the key technology behind the entire Vizion range. The construction uses a specific rear section, spoiler and heel mechanism that allows the boot to open significantly wider and create a large entry area for the foot.

Once the foot is inside, the system closes and the rear section provides the support required for skiing. The main advantage is therefore the ability to combine easy entry with a construction that is ready for performance-oriented loads once secured. This principle is what distinguishes the Vizion from conventional ski boots with a traditional overlap shell.

Polyether shell, Steel Spine and bi-injected spoiler

The boot is built around a POLYETHER shell complemented by DUAL CORE, a STEEL SPINE reinforcement and a BI-INJECTED SPOILER. These elements work together to create a performance construction that must satisfy two very different requirements – opening widely for easy entry and then providing strong support while skiing.

The cuff uses POLYURETHANE. The entire construction is designed around the Vizion concept so that easier entry does not come at the expense of the 120-flex character or the precision required for performance skiing.

FULL CUSTOM PRE-SHAPED LINER, SEAMLESS TOEBOX, THINSULATE

The FULL CUSTOM PRE-SHAPED LINER is pre-shaped with an emphasis on precise foot positioning and comfort. Its construction is complemented by a SEAMLESS TOEBOX, which creates a cleaner seamless area around the toes, and THINSULATE insulation focused on thermal comfort.

The liner therefore follows the overall Vizion philosophy – a performance ski boot should not only deliver strong skiing characteristics but also remain practical and comfortable throughout a full day on the mountain.

DOUBLE BUCKLE and the Vizion closure system

The technical specification lists DOUBLE BUCKLE as the closure system. It is an important part of the specific Vizion mechanism and works together with the opening rear construction of the boot.

When opened, the system allows substantially more space for the foot to enter. Once closed, its role is to provide the secure retention required for power transmission and effective use of the 120 flex. The closure construction is therefore directly connected to the model’s central idea – making entry easier without sacrificing the support required while skiing.

GripWalk and off-ski practicality

The Vizion 4B Pro 120 MV GW features pre-mounted GripWalk soles with a rubber tread and articulated toe. When walking without skis, they support a more natural foot movement and more practical contact with the ground.

Combined with Step In Technology, this is another feature that improves everyday usability. Easier entry and more convenient walking are useful in the parking area, on the way to the lift or when moving around the ski resort. For skiing, GripWalk-compatible bindings are required.

100 mm + flex 120: performance without a race-narrow fit

The combination of a 100 mm last and 120 flex is one of the main reasons for this model’s versatility. The flex provides enough support for an experienced performance skier, while the Medium Volume construction offers more space than typical narrow race-oriented models.

The Vizion 4B Pro 120 MV GW therefore makes sense for skiers who want a high-performance boot for dynamic all-mountain skiing but prefer a more versatile 100 mm fit and do not want to struggle with getting into a stiff conventional performance shell every day.

The manufacturer specifies a weight of 2.045 kg per boot, manufacturer code RBN7030 and product code N24001488.
