Thunder GTX — Men's

With a Vibram® Hero outsole and the Adaptive Hero System, the all-new Thunder 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.
