Flux Adapt Waterproof Runner

Stay dry. Stay natural. The Adapt Waterproof Runner keeps rain out without turning your feet into saunas. A stretchy waterproof lining sits behind the breathable AdaptKnit™ upper, so you get weather protection and airflow at the same time—on a zero-drop platform that feels connected and balanced.
