The Alterra GTX is a versatile trekking shoe designed for treks of moderate difficulty and duration over mixed terrain. What I love most about it is that it's breathable, so you don't get blisters or pressure points and are free to enjoy the climb.Florian Westermann - Keller Sports Pro
The Vibram® Octopus outsole has an asymmetrical structure and comes equipped with AKU's exclusive Elica technology. This technology guarantees excellent load distribution throughout the foot and improves transitions.
The Alterra GTX's suede upper was made without a gusset. It comes with a stretchy tongue and collar to provide a comfortable fit. Liba® Smart PU protects the upper material from damage.
This model's GORE-TEX® Performance Comfort lining is both breathable and waterproof at the same time. For you, this means enjoying long, challenging treks without worrying about sweat-caused blisters.
