A true icon of the mountains, the Vioz GTX is where Italian craftsmanship meets uncompromising backcountry performance. Built with rich Hydrobloc® full-grain leather and a time-proven silhouette, this best-selling hiker delivers a confident blend of stability, comfort, and precision for steep ascents, technical descents, and long miles under load.
The exclusive Zamberlan® Vibram® 3D outsole drives powerful downhill braking and a smooth, rock-forward stride, while the ZFS (Zamberlan Flex System) allows natural forward flex without sacrificing lateral support. Inside, GORE-TEX® Performance Comfort keeps feet dry and breathable in changing conditions, and the ZBPK Performance Fit cradles the heel while preserving toe-room for all-day comfort. Resolable and crafted in Italy, the Vioz GTX is a legacy boot built to earn its scars.
