The Earth has long been our playground. It continues to provide for us, and when you lace into these adidas by Stella McCartney running shoes you're doing more than showing up for yourself, you're showing up for the planet. A small way to return the favour, and a big part of our commitment to help end plastic waste. The adidas PRIMEKNIT upper wraps the foot in total comfort — championing your stride and adapting to the changing shape of your foot as the miles fall behind. Miles that feel like almost nothing, we might add, since plush BOOST cushioning takes the energy you put in and returns it right to you. 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.
