DetailsExplore new zones.When the same old sheep trails leading out of the resort gates no longer tickle your sense of adventure, buckle up the Salomon Women's MTN Explore Ski Boot and set your own skintrack into those remote and far-flung backcountry zones. Designed to remain nimble on the up, comfortable during long, contouring skintracks, and dependable on the descent, Salomon's MTN Explore Boot is a solid offering any backcountry-roaming skier will appreciate. Salmon's long been known for it's hard-charging line of alpine boots, but when it came out with its all-new series of backcountry-specific boots, folks were forced to rethink what they thought they knew about Salomon boots. Striking a healthy balance between weight savings and downhill performance, Salomon integrated several new technologies into this boot to make it a well-rounded backcountry tool. For starters, Salomon built the shell around its Sensifit shell technology, which eliminates needless materials throughout the shell but reinforces it in key areas to maintain a progressive and responsive flex while skiing. When coupled with the lightweight carbon spine, the MTN Explore delivers big on the descent, without sacrificing an ounce of performance on the ascent. In terms of fit, the MTN Explore features a narrow 98mm last and easy-flexing 90 flex index ideal for lighter skiers that plan on being in this boot for upwards of eight hours a day hiking for the best snow and most aesthetic lines. The women's-specific liner and cuff is shaped to match narrower legs and calves and is slightly shorter in height to better fit the female leg. And if that wasn't enough, Salomon made the liner heat moldable to ensure a precise and snug fit through the heel, arch, and toe box. With 64 degrees of cuff rotation, the MTN makes short work of bootpacks and long skintracks, and the well-designed buckle layout is specifically designed to trim time from your transitions with just two lightweight aluminum buckles that can be quickly fastened and a horizontal ski/walk mode latch that can by quickly engaged with a quick flick of the wrist when it's time to lock things tight and ski your line.A backcountry-specific boot built for accessing remote lines90 flex index puts an emphasis on comfortNarrow 98mm last with a shorter and narrower cuffLiner is heat moldable for a snug and precise fitTwo aluminum buckles save weight and transition timesCarbon spine reduces weight while keeping the boot stiffSurelock mechanism locks cuff into ski modeLugged rubber sole crawls up icy bootpacks and rocky ridgesItem #SAL00UGTech SpecsShell Material[shell] Grilamid, [cuff] polypropylene, [spine] carbonFlex90Last Width98 mmBuckles2Buckle MaterialaluminumWalk Modeyes, 63-degree cuff rotationLinerWomen's Ultralight CF 3DThermo-moldable LineryesLiner Closurequick laceBinding CompatibilitytechSolerubberClaimed Weight[single, size 24.5] 2 lb 13 ozRecommended Usealpine touringManufacturer Warranty2 years
