The iconic Ultraboost running shoe has been continually evolving since it debuted in 2015. So it's fitting that this version aligns with our goals for the future — creating products made with renewable materials to help end plastic waste. Don't worry, they still have all the tech that makes them one of the most comfortable shoes ever, including responsive BOOST cushioning and foot-hugging adidas PRIMEKNIT. Plus, they have a narrower heel fit and lower instep curve for a snug feel. Wear them running. Wear them walking. Wear them anywhere because they feel good in every way. These shoes are made with natural and renewable materials as part of our journey to design out finite resources and help end plastic waste.
