We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.The Primus Flow features an innovative 4mm midsole made entirely from low-density ETPU that’s designed to reduce the risk of injury without sacrificing proprioception. However, remember that barefoot running is a journey, not a race. To prevent injury, take it slow – learn how to stand, walk and squat barefoot first before attempting to run.Training Barefoot performance for your best performance.
