Take the lead and never look back. The release of the Ultraboost in 2015 was a seismic jolt to the world of running shoes. These adidas shoes update the legacy and further refine it. The knit upper adapts to the changing shape of your foot as you run and has stitched-in areas of reinforcement for a locked-in feel. Responsive cushioning adds energy to your stride and inspires you to add that extra loop. Good for the oceans Primeblue features Parley Ocean Plastic® which is made from recycled waste that's intercepted from beaches and coastal communities before it reaches the ocean.
