The Primus Trail Knit FG Grounding does everything great trail footwear should. Designed for natural movement on mixed terrain, its thin Firm Ground sole balances grip with barefoot sensation, helping you build strength while staying connected to the trail. A breathable knit upper allows feet to move freely while helping keep debris out. Built with grounding conductive materials, it offers an even more direct connection to the ground for those seeking a deeper barefoot experience.
