With a Vibram® Hero outsole and the Adaptive Hero System, the all-new Thunder GTX Women's boot offers the highest levels of comfort, stability, grip, and protection of medium difficulty hiking on mixed trails. Developed for the Thunder, the new Adaptive Hero System acts with each step, ensuring stability and cushioning on different surfaces while giving more energy to movement without tiring the foot. AHS sandwiches a TPU insert between two low-density layers of EVA in the midsole. The soft upper layer gives your foot a cushioning effect while walking, while the bottom layer absorbs negative impact with the ground, adapting easily to uneven terrain.
For steep, looser terrain, the Vibram® Hero outsole's deep, multi-directional lugs and pronounced heel keep you steady in any conditions. The Thunder uses Hydrobloc-treated suede uppers, backed by GORE-TEX® Performance Comfort membranes for waterproof, breathable comfort guaranteed for the life of the boot. Handmade to be your ideal trail companion, the Thunder GTX is lightweight and comfortable, designed, built, and backed by the bootmaking expertise developed by three generations of Zamberlan family in Italy.
