The Hanwag Men's Altai GTX Backpacking Boot excels on long, muddy, rocky trails, especially with a heavy load on your back. Its Gore Tex lining gives guaranteed waterproof breathable protection, and the suede Cordura upper stays strong for many seasons. Vibram's AW Integral sole provides superior traction while remaining very flexible for a smooth stride over rough terrain. Ghilly Lacing ensures a tight fit that won't compromise mobility or flexibility, and the Air Pulse System circulates airflow from the tongue to the footbed. A cemented construction makes resoling the Altai as easy as can be.
