Energy is more than mere fuel—it’s the creative power to imagine a better you. In 2013, we launched the technology that changed running forever. Comprised of thousands of energy capsules, Boost defined a new era of cushioning. Made with this unprecedented technology, the adidas Ultraboost became the first running shoe to deliver energy return with every step. The more energy you give, the more energy Boost returns.
