Curiosity drives creation. Born for city exploration, this version of the adidas NMD_R1 is the cutting-edge evolution of the '80s-inspired running shoes. A stretchy knit upper crafted from recycled materials hugs your foot for comfort on the go. Long commutes and slick city sidewalks are no problem, thanks to the grippy rubber outsole and Boost midsole beneath your feet. 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.
