Engineered to connect you with the ground and engage every muscle
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.
