From quick lunchtime miles to your next 10K race, the new Ultraboost Light 23 is a responsive ride perfect for city runners. You'll feel the difference the moment you step into these adidas by Stella McCartney performance running shoes. They are super lightweight — with a breathable monomesh upper and the most lightweight BOOST cushioning yet.

The carbon footprint of this pair of shoes has been reduced by a minimum of 10% when compared to its previous version. Less greenhouse gas emissions, including CO2, for the full life cycle — from creation all the way to end-of-life. 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.
