The Adidas Men's Terrex Fast GTX Surround Hiking Shoe is a light hiker that surrounds your entire foot with waterproof, breathable Gore-Tex Surround. Most membranes only laminate the shoe's upper with waterproofing because shoe's would lose too much breathability with a membrane underfoot. Gore-Tex Surround not only includes waterproofing underneath the foot, so no water seeps in at the sole, but also remarkably amplifies breathability in a way that waterproof footwear has never seen. By placing mesh inserts deep in the Continental rubber sole, Gore-Tex Surround boosts ventilation and still blocks water from seeping through. The result is a shoe you can rely on during rainy hikes, and still enjoy a warm summer stroll up to a summit.
