The adidas Outdoor Men's Terrex Free Hiker is a lightweight athletic hiking boot that incorporates the comfort and forgiving fit of stretch-knit fabrication while also providing waterproof protection! The boot's upper is constructed of seamless Primeknit synthetic fabric and utilizes abrasion-resistant welding to enhance durability. The stretch-knit cuff provides a close comfortable over-the-ankle fit. An integrated GORE-TEX Performance Comfort membrane delivers breathable waterproof protection to keep feet dry and comfortable. A responsive BOOST foam midsole cushions every foot strike and even provides an energy return that reduces fatigue and keeps legs fresher longer. Internal stabilization helps to enhance lateral stability and support the midfoot. The boot's Continental rubber outsole is highly durable and provides excellent traction on varied surfaces.
