The Adidas Hyperboost GTX running shoes use a GORE-TEX Invisible Fit membrane built directly into the shoe rather than added as a separate layer, blocking rain and wind without adding bulk underfoot. Boost+ foam cushions every stride the same way it does on adidas's standard trainers, so weather protection doesn't come at the cost of the ride. A Continental rubber outsole grips confidently across wet pavement and varied surfaces, backing up the shoe's all-weather claim from the ground up. What Our Gearhead® Experts Are Saying:"I ran through sideways rain and wind that would've soaked through a normal shoe in minutes, and my feet stayed completely dry the whole run. I couldn't tell the membrane was even there until I needed it."
