These adidas shoes go way beyond comfort by harnessing your energy and returning it back to you. That's thanks to the BOOST midsole, which offers superior cushioning and a springy ride. The adidas PRIMEKNIT upper wraps a supportive fit that enhances your movement, and Torsion System offers midfoot stability for a secure, comfortable stride. A Continental Rubber outsole provides outstanding grip, even in wet conditions. You're officially ready to step it up. 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.
