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.

The Primus Lite 3.5 is our original training all-rounder, reimagined with a new upper to get us closer to circularity. Made for moving naturally and building natural strength during runs and wide-ranging training disciplines, it’s perfect for experienced barefoot cross-trainers and those new to barefoot performance.
