The Rossignol Vizion 4B Pro 100 MV GW takes the brand's step-in shell design and pairs it with a medium flex aimed at intermediate to advancing skiers. This men's all-mountain boot opens at the rear cuff for easy entry, then locks into a traditional four-buckle overlap stance, with a polyurethane shell and medium-volume last sized for average feet. The combination delivers real downhill performance without the entry hassle and without the stiffness of a top-tier boot.

Why we like it:

Step-In Technology is genuinely the difference-maker here. Anyone who has stood in a cold lodge bench trying to cram a frozen polyurethane cuff over their heel will understand the appeal of a boot that opens up at the back for entry. Bonus: this version's softer flex and friendlier price still gets the same Dual Core shell construction and Generative Design used on the high-end Vizion models.

Who it's for:

Intermediate to advancing skiers with medium-volume feet who want a modern all-mountain boot without committing to a 120-flex experience. The 100 flex is a sweet spot for solid weekend skiers and people who ski a few weeks a year; it's responsive enough to drive shaped skis but forgiving enough to handle a long day without hammering shins.

Highlights:

The shell is the headline: a traditional overlap structure with a wide-open rear that articulates back for foot entry, locked down by a rigid Steel Spine and the Double Buckle cable mechanism. This is Rossignol's approach to solving the easy-entry problem without going to a rear-entry or cabrio design, and the resulting boot skis like a normal four-buckle overlap. Polyurethane shell construction delivers reliable performance at a friendlier weight and price than the polyether-shelled top model, and Generative Design Structure trims wall thickness where the load math allows. Dual Core molding pairs softer polyurethane with harder plastic in the same shell for a progressive flex that doesn't feel boxy. The pre-shaped liner with double strap is fitter-friendly and warm, and GripWalk soles ship premounted.

Things to consider:

Stronger advanced and expert skiers may want more flex than the 100 delivers; the Vizion 4B Pro 120 MV is the natural step up. Wide-footed skiers will fit better in the Vizion 4B 100 HV at 102mm.

Fit & sizing considerations:

Sizes true to mondopoint, so go with your normal Rossignol alpine size. The 100mm last sits in medium-volume territory and should suit average-width feet without significant work. A bootfitter session for shell prep and footbed work is always worth it but isn't as critical at this flex as it is on the stiffer top-end boots.
