The best ideas? They stick around and evolve. Just look at adidas' Ultraboost running shoes. They may have started as high-performance runners, but they quickly gained a following off the track. This pair builds on their design code in a version dedicated to lifestyle wear. Running or walking, Boost cushioning delivers energy return you have to feel to believe. This product is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic. 50% of the upper is textile, 75% of the textile is Primeblue yarn. No virgin polyester.
