You run. We innovate to make it feel easier. That's where the adidas Ultra 4DFWD shoes come in, combining our adidas 4D midsole with the beloved adidas PRIMEKNIT upper. Their unique lattice structure compresses at impact, redirecting your energy into forward motion. Whether you're running near or far, fast or slow, you get a smooth ride that feels more like gliding than pounding on pavement. This shoe's upper is made with a high-performance yarn which contains at least 50% Parley Ocean Plastic — reimagined plastic waste, intercepted on remote islands, beaches, coastal communities and shorelines, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
