This adidas Ultraboost running shoe serves up comfort and responsiveness. You'll be riding on a BOOST midsole for endless energy, with a Linear Energy Push system and a Continental Rubber outsole. This shoe's upper is made with a high-performance yarn that contains at least 50% Parley Ocean Plastic - reimagined plastic waste, intercepted on remote islands, beaches, coastal communities, and shorelines, to prevent it from polluting the ocean.
