The ultimate expression of speed on a tennis court. These adidas Adizero Ubersonic shoes support extreme lateral movements with a reinforced, lightweight mesh upper. Underneath, a responsive Lightstrike midsole and grippy Adiwear outsole combine to back up instinctive play on hard courts. Areas prone to abrasion are covered in an Adituff abrasion zone that includes recycled BOOST material so you can go all out, game after game. 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.
