When the adidas Ultraboost debuted back in 2015, it had an impact that spilled beyond the world of running. For this version of the shoes, adidas retooled the design on a 3D-printed midsole. The denser parts of the lattice provide more support, and the parts that are open feel more cushioned. This product is made with Primegreen, a series of high-performance recycled materials. 50% of the upper is recycled content. No virgin polyester.
