When it comes to trail runners, “barefoot” often conjures images of gnarly off‑road races and mud‑splattered feet. Vivobarefoot’s new Primus Trail Flow flips this image on its head.
Instead of layering foam, insoles and overlays, the Flow pares back to a 3 mm puncture‑resistant sole, a 100% recycled mesh upper and minimalist rubber lugs, offering a true barefoot experience.
