Vivo Barefoot Primus Trail III All Weather FG Men's Trail Shoes

The Primus Trail III All Weather FG is Vivobarefoot's feet-first trail runner built for cooler, wetter conditions and mixed hardpack terrain. A zero-drop, ultra-thin sole keeps genuine ground feel while a Firm Ground outsole with a textured arch and sticky rubber compound grips wet rock, loose gravel and firm trail alike. The non-wicking, water-resistant upper sheds rain and puddle splash without a membrane, so it stays breathable on long days, and a quick-lace toggle system gives a secure, no-fuss fit on the move. The wide, foot-shaped design lets toes splay naturally for stability and sensory feedback. Suits trail running, fastpacking, fast hiking and day walks in variable, wet-weather conditions.
