A four-buckle overlap boot that opens like a rear-entry. Rossignol&';s Step-In design lets the spoiler and spine articulate rearward so you slide your foot in without wrestling a cold shell in the lift line - then locks down and skis like a conventional alpine boot. The 102mm high-volume last makes this the forgiving end of the Vizion range, built for wider or higher-volume feet that get pinched in a performance last. The 120 flex is the stiffest offered in the high-volume shell, so you get real support for driving a ski without giving up the roomy fit. Best for: intermediate to advanced all-mountain skiers with wider feet, and anyone who&';s tired of fighting their boots on and off. Features Step-In Technology - the cuff and liner recline to open the back of the boot wide for hands-free entry and exit Spine Link Mechanism - the double buckle flips into ski position and locks the spine, restoring full four-buckle support Steel Spine - internal steel reinforcement at the rear for stability and power transmission Dual Core construction - two plastics injected simultaneously for livelier rebound and a smoother, more controlled flex than a single-density shell Bi-injected spoiler - two hardnesses for better wrap and comfort around the calf Step-In Vizion liner - preshaped and heat-moldable, with elasticated zones that follow the cuff as it tilts back Forefoot Thinsulate stretch - insulation where your toes need it Seamless toe cap - removes pressure points and cuts heat loss GripWalk soles, premounted Specifications Flex: 120 Last: 102mm (High Volume) Shell: Dual Core, 4-buckle overlap with Step-In Sole: GripWalk Color: Blue Binding compatibility - important. GripWalk soles work with GripWalk-compatible alpine bindings and with touring bindings meeting ISO 13992. They are not compatible with standard alpine bindings (ISO 9462). Bring your skis in and we&';ll confirm before you buy. Sizing. Ski boots are sized in mondo point - the length of your foot in centimeters. There&';s no true half size: 27 and 27.5 are the same shell. Boots should feel snug, with your toes brushing the end when you stand upright and pulling back when you flex forward. If you&';re unsure, come get shell-fit - it takes ten minutes and it&';s the difference between loving and hating a boot.
