The Terrex Free Hiker shoes are designed for performance and comfort and built for the journey ahead. An adidas BOOST midsole provides superior cushioning and energy return, so you can feel comfortable and confident on long adventures in the mountains. An internal frame adds lateral stability as you navigate rocky trails and uneven surfaces, supporting your midfoot with every step. For moving fast over wet or dry terrain, the Continental Rubber outsole provides grippy traction, so you can feel secure in your footing. Whether you're out for a day-long expedition or you're spending the weekend covering long distances above the tree line, a sock-like fit delivers comfort over any surface or distance.
