Offering incredible comfort and freedom of movement, the adidas Outdoor Men's Terrex Free Hiker GTX is a lightweight hiking boot with weather protection to take on any trail conditions. The lightweight and athletic design still provides the support and protection needed during extended hikes. The boot's snug and stretchy Primeknit synthetic upper utilizes abrasion-resistant TPU welding to enhance durability while still providing a comfortable sock-like feel. A stretch-knit cuff offers a close, comfortable over-the-ankle fit. The GORE-TEX waterproof/breathable membrane integrated in the upper protects your feet against wet conditions and rainy trail days. A responsive BOOST foam midsole cushions every foot strike and even provides an energy return that reduces fatigue and keeps legs fresher longer. An EVA stabilization frame and torsion bar increase stability without adding unnecessary weight or bulk. The molded heel cap further enhances the stability and secure fit of the boot. The Continental rubber outsole is highly durable and provides excellent traction on varied surfaces.
