Ultraboosts are a favorite around the world. The adidas BOOST midsole cushioning gives you excellent energy return through every step, while the adidas PRIMEKNIT upper wraps your foot snugly in place. Torsion System adds support and stability at the midfoot. No matter where you may be heading, these juniors' adidas sneakers keep you comfortable. 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.
