What Our Gearhead(R) Experts Are Saying:"I've never worn a boot that blends comfort and performance this smoothly. The Vizion 4B Pro 100 MV GW opens up like a slipper but locks down tight when it's time to ski hard. It's ideal for those who want performance without the daily battle of boot entry."We've all wrestled with ski boots in the lot or lodge-but the Rossignol Vizion 4B Pro 100 MV GW Ski Boot puts an end to the struggle. With a revolutionary Step In design, this boot opens wide at the cuff for effortless entry and exit. Whether it's first tracks or apres laps, it gets us out faster and skiing longer. Once we're locked in, there's no compromise. The Dual Core polyether shell and Spine Link Mechanism deliver powerful energy transmission, while the bi-injected spoiler hugs the leg for responsive support. Inside, a fully custom liner with Thinsulate(TM) Stretch insulation keeps our feet warm and locked in without hot spots. Medium volume, high precision, and absolute ease-that's Vizion.
