act running

Founded in Paris in 2025 by designer and runner Thibault, ACT Running merges high-performance athletic wear with radical environmental accountability. The founder’s background as a runner directly informs the brand’s ethos of creating functional, beautiful, and sincere clothing that transitions seamlessly from high-intensity movement to everyday life. ACT Running challenges the industry standard by utilizing plant-derived materials, such as its proprietary BioPerf™ nylon made from castor beans, which significantly reduces carbon emissions compared to conventional synthetics.
