Both GORE-TEX versions of these respective models offer excellent protection from wet weather, although breathability is greatly reduced in hot conditions. Therefore, I would opt for the non-GORE-TEX version of either shoe if you want increased ventilation and airflow, particularly during the summer months.

It was first patented by Kinetic Chemicals in 1941 and trademarked as Teflon. One of its first uses was as a seal coating in uranium enrichment for the Manhattan Project. Later, Teflon was used for cookware. The good news is for most people, weight differences are pretty negligible. For example, the Salomon Ultra 4 GTX weighs 380 grams, and the nonwaterproof Ultra X 4 weighs 360 grams. Nonetheless, Gore-tex hiking shoes continue to outperform the rest. But why is Gore-tex so good? Because the science of Gore-tex is astonishing.

If the show is waterproof but does not include GTX, then it uses other materials for its waterproofing. Is Gore-tex the only waterproof fabric? Starting in 1958, Bill and Genevieve Gore were onto something special. They were curious about a revolutionary and new polymer called polytetrafluoroethylene (PTFE). PTFE is a synthetic polymer called a fluoropolymer. It’s well known for being hydrophobic, having a high melting point, and resistant to abrasion via a high tensile strength. High-quality materials are used in Adidas TERREX items to ensure you are ready for any weather. GORE-TEX®, for example, is both waterproof and breathable, making it excellent for long journeys. Polartec Alpha also performs well in terms of moisture control and breathability, ensuring that you keep warm without overheating. A decade later, in 1969, the Gores’ son, Bob Gore, discovered what eventually became known as expanded polytetrafluoroethylene, or ePTFE for short. To create ePTFE, Gore stretched the PTFE under certain conditions. What he created was a heat-resistant, hydrophobic, and thin fabric. Can a Gore-Tex hiking shoe be lightweight, comfortable, and supportive? It sure can! Our best overall Gore-Tex hiking shoe is the Salomon X Ultra 4 GTX, which takes first place for its instant comfort straight out of the box, perfect cushioning, and first-rate support.

No, shoe manufacturers incorporate many other waterproof fabrics into their hiking shoes. For example, Columbia Sportswear uses its patented OutDry and Omni-tech technology to waterproof footwear. With that being said, however, Gore-tex continues to be the industry’s gold standard when it comes to waterproofing, which explains its higher cost. Thanks to a tried and reliable Gore-Tex textile lining, these hiking shoes are waterproof. Although they only have a flood height of 3 inches, they keep water out of your shoes when crossing shallow creeks and muddy pathways. 3. Traction There isn’t a lot we would change here – the only issue we noted is that the Adidas Terrex Swift isn’t the most breathable hiking shoe in the world, due to its sturdy build and waterproof membrane. Personally, we’d save it for use from autumn through to spring, and switch to a more lightweight and breathable hiking shoe such as the Salomon Vaya for hiking mountain trails in hot dry weather. For this special selection, we employed our outdoor expertise and hiked hundreds of miles to field-test all the Gore-Tex hiking shoes in our inventory. That means wearing each pair on actual hiking trips, covering 30+ miles across wet trails and muddy routes. Our selection process includes:Weighing in at just 13.3 oz (378g), its featherweight translates to more mileage on our hikes before our feet get tired. When we compared it to our lab-tested waterproof hiking shoes, we found it is 5% lighter than average. It even sneaks in below the average for non-waterproof shoes. Impressive for a completely watertight shoe! We even tested its impermeability by standing in a stream, and our feet stayed totally dry. That’s a win for the Gore-Tex! The unique mesh and synthetic materials of the TERREX shoe range contribute to a comfortable foot environment. Perspiration is routed away, to ensure a dry and comfortable shoe even after hours of jogging. Both adiPRENE® and TORSION® provide extra heel or midfoot stability, for traction on all types of surfaces. Even after many hours of exertion, the EVA midsole softly cushions every step. Final verdict Both the Free Hiker and Swift R3 hiking shoes feature the trusted Continental™ rubber grip on the outsole, a standard feature of all adidas Terrex trail shoes. However, the Swift R3 has a slightly more aggressive grip pattern and a slightly deeper lug. Both models have a 10mm drop but the outsole is divided into two parts on the R3 with a deeper heel than the Free Hiker.
