adidas Every run builds off the one before it. These running shoes ride on 17 years of data, with a design that makes progress feel like something you can chase and catch. The 3D-printed 4D midsole redirects energy forward, making your gait feel more like a glide. The adidas Primeknit+ upper works in tune with the midsole, giving you the support for a smooth, effortless stride. The rubber outsole is designed to work in harmony, providing superior traction. This product is made with Primegreen, a series of high-performance recycled materials. 50% of upper is recycled content. No virgin polyester.
