adidas Terrex Fast GORE-TEX Surround Walking Shoes Built for trail running, the adidas Terrex Fast GORE-TEX Surround Walking Shoes feature a waterprrof upper, hardwearing outsole and plush SURROUND midsole. GORE-TEX technology uses a waterproof but breathable membrane to protect you from the outdoor elements. GORE-TEX Upper Engineered using a GORE-TEX upper, the adidas Terrex Fast walking shoe is undeniably breathable and durably waterproof to keep your feet dry and comfortable in all conditions. Additionally, the upper is abrasion resistant and offers protection against sharp rocks and roots that you'll undoubtedly encounter on the trails. Protective weldings enhance this durability, while also offering increased stability on uneven ground. Lastly, lace bungee stows are conveniently placed to help avoid tangling of laces and for ease when getting your boots on or off. GORE-TEX Surround Midsole The patented, open construction in the midsole walls allows moisture to escape from below the foot and through the GORE-TEX laminate. From there, it escapes out of the boot via the side ventilation panels to enhance breathability and keep your feet drier in warm weather. Therefore, your sense of well-being will be increased while you're out and about, as having dry feet minimises chafing and blisters, which can often be extremely uncomfortable. An Ortholite sockliner also features to offer extreme comfort by supporting the structure of your foot. Through advanced proprietary technology, Ortholite's polyurethane and recycled rubber-based formula holds the distinction of being the only open cell foam insole to combine long-lasting cushioning, breathability and durability. Continental Rubber Outsole The Continental Rubber compound offers maximum traction on a variety of different surfaces. The highly durable compound allows you to grip the ground beneath in both wet and dry conditions to reduce the chance of you slipping. A TPU heel clip has also been incorporated i
