Built for speed, these women's Adizero Ubersonic tennis shoes from adidas have a lightweight mesh upper that's reinforced for stability during extreme lateral movements. High-abrasion areas are covered with recycled BOOST material for added durability. Their Lightstrike midsole and Adiwear outsole ensure blink-quick responsiveness on hard courts. 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.
