Take on your next walk around the block or that weekend out with friends in these Ultraboost shoes. They have a soft adidas PRIMEKNIT upper that wraps around your foot so you can move freely. A plush BOOST midsole energizes every step while a Stretchweb outsole flexes naturally for a springy and comfortable ride. This shoe's carbon footprint has been reduced by 43%, compared to previous versions. Less greenhouse gas emissions, including CO2, for the full life cycle — from creation all the way to end-of-life.
