{"product_id":"rossignol-vizion-4b-80-pro-mv-w-boots-2027","title":"Rossignol Vizion 4B 80 Pro MV W Boots 2027","description":"\u003ch2\u003eThe Boot\u003c\/h2\u003e\u003cp\u003eThe Rossignol Vizion 4B 80 Pro MV W is a \u003ca href=\"\/collections\/womens-ski-boots-1\"\u003ewomen's ski boot\u003c\/a\u003e built around one genuinely clever idea: you should not need to fight your way into a four-buckle alpine boot. Rossignol's Step-In system uses a Spine Link Mechanism and a Steel Spine to hinge the cuff wide open at the back. Slide your foot in, flip the Buckle, and the shell locks into a full traditional skiing position. No yanking, no wedging, no sitting on the floor of the base lodge.\u003c\/p\u003e\u003cp\u003eIt's a 100mm last — medium volume, so it holds the heel and ankle firmly without crushing a normal-width foot. Flex is 80, which sits right in the intermediate-to-advancing-intermediate range. The shell is a standard two-piece overlap design; the Step-In magic is all in the spoiler and spine hardware, not some softened-up shell that trades away edge response.\u003c\/p\u003e\u003ch2\u003eWho it's For\u003c\/h2\u003e\u003cp\u003eIntermediate women skiers who are logging real days and want a boot that performs without punishing them to put on. If you're comfortable on blue runs and starting to work greens-to-blacks on a good day, the 80 flex gives you enough support to push, and the 100mm last will suit most average-width feet well. Skiers with a genuinely wide or low-volume foot will want to try it on — the medium last is true to spec and won't stretch to cover a wide forefoot.\u003c\/p\u003e\u003cp\u003eIf you're already skiing expert terrain hard and want a stiffer drive, the Vizion line goes higher — the 80 is not that boot. But for skiers building mileage and wanting to focus on the mountain rather than their feet, this is a strong match.\u003c\/p\u003e\u003ch2\u003eFlex \u0026amp; Fit\u003c\/h2\u003e\u003cp\u003eAn 80 flex for a women's boot reads as medium — not beginner-soft, not race-stiff. It'll give you resistance when you push into a turn and forgive you when you're a little back-seat on a steeper pitch. On snow, that translates to a boot that responds without being demanding.\u003c\/p\u003e\u003cp\u003eThe liner is pre-shaped and thermoformable, with Thinsulate insulation in the forefoot and a fleece-and-merino-wool lining. Warm in real cold, and the thermoform means a bootfitter can dial it to your foot rather than relying on break-in time alone. Cant adjustment is included, so we can tune the forward lean angle to match your stance. Bring the boot in and we'll set it up right — our \u003ca href=\"\/pages\/ski-and-snowboard-boot-fitting\"\u003eexpert boot fitting\u003c\/a\u003e is the most important step anyone skips.\u003c\/p\u003e\u003cp\u003eSizing runs in Mondopoint. A 24.5 mondo fits a roughly 245mm foot, which is approximately a US women's 8. When you're between sizes, the 80 flex tends to pack out a little over the season, so fitting snug at the toe at first is normal and expected.\u003c\/p\u003e\u003ch2\u003eTech that Matters\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eStep-In Technology.\u003c\/strong\u003e The Spine Link Mechanism releases the Steel Spine, the cuff tilts back, and the whole boot opens wide enough to walk your foot straight in. Flip the Double Buckle to lock it closed. No performance compromise — once shut, it skis like a conventional overlap boot.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e100mm MV Last.\u003c\/strong\u003e Medium volume means real heel-pocket hold and ankle control without a narrow toe box. It's the sweet spot for a skier with an average foot shape who doesn't want to choose between comfort and precision.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThermoformable Pre-Shaped Liner.\u003c\/strong\u003e Heat-molding in the shop lets us eliminate pressure points before your first run. The Thinsulate and merino lining keeps warmth up on cold mornings without adding bulk that fights the fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGripWalk-Compatible Sole.\u003c\/strong\u003e The outsole works with GripWalk-compatible bindings for a more natural walking motion getting to and from the lift. It's a meaningful comfort upgrade over a flat alpine sole on a long resort walk.\u003c\/p\u003e\u003ch2\u003eWhy Willi's\u003c\/h2\u003e\u003cp\u003eWe've been fitting ski boots since 1970, and boot fit is still the single biggest thing that changes how someone skis.
