True to the Zero G spirit, the award-winning Zero G Tour Pro, a stiff touring boot for experienced backcountry skiers, provides best-in-class performance for the weight. Thanks to a carbon fiber cuff and Grilamid shell, it weighs in at just 1,320 grams (at a size 26.5)?the lightest in our Zero G collection and a fraction of the weight of most ski boots. An uber-wide 55-degree range of motion makes a hike up or a skin out feel like a walk in the park. And yet, when you lock down the four buckles for the descent, the Zero G Tour Pro?s true 130 flex shines, making this touring boot second to none in downhill performance. Minimal resistance for the up and confident turns on the down, Zero G Tour Pro is the chosen boot by some of the world?s most accomplished ski mountaineers. All of sudden, the mountains on the horizon don?t seem so far away.
