Lightweight and cushioned, these adidas running shoes are built with a flexible adidas PRIMEKNIT upper set on an energy-returning BOOST midsole. A classic lace-up front gives them a secure fit, so you can wear them comfortably all day long, all time of the year. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic - reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
