Celebrate two world-of-sport icons. These running shoes bring together storied footballer Mohamed Salah and the time-tested Ultraboost. Salah graphics dress up the tongue. adidas BOOST delivers incredible energy return and instant comfort while the adidas PRIMEKNIT upper wraps the foot with a supportive fit that enhances movement on the pitch and all across town. 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.
