These men's running shoes have a flexible and supportive build to take on the most demanding runs. They're made with BOOST Light, our lightest BOOST ever — more than 10% lighter — with even more energy return and cushioning. The foot-hugging adidas PRIMEKNIT+ upper is forged for incredible support. 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.
