The Primus Flow is the newest member of the Primus family, designed for pinnacle barefoot running performance. Built for efficient and unrestricted natural movement, this ultra-lightweight runner – our lightest ever – weighs in at just 150g. Its lightweight, breathable upper made from engineered recycled mesh forgoes overlays in favour of a stripped-back, seamless construction.

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.
