Light, supportive and energized, the Ultraboost Light Shoes are here to help you go the distance in comfort. The Light BOOST midsole is a new generation of adidas BOOST and our lightest one yet, delivering epic energy in every stride. The Linear Energy Push system adds extra stability and the PRIMEKNIT+ and Forgedmesh upper, provide smooth comfort and distraction-free movement. Lace up in these shoes and celebrate the euphoria that comes from running. 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, preventing it from polluting our ocean. The other 50% of the yarn is recycled polyester.
