These ultraboost running shoes serve 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 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.
