Primus II FG Running Shoe – Men's

For runners building real foot strength on technical singletrack, the Primus Trail II FG is our go-to minimalist trail shoe for athletes who want genuine ground connection. A puncture-resistant sole with firm-ground lugs delivers traction and proprioceptive feedback without killing the feel, while the wide toe box lets your foot splay and work naturally over miles.

• Ultra-thin, puncture-resistant sole gives you real terrain feedback on rooted and rocky trails without sacrificing underfoot protection
• Firm-ground lugs bite into technical singletrack and mixed surfaces, keeping you planted where grip matters most
• Zero-drop platform promotes natural foot mechanics and takes load off your calves and knees on longer efforts
• Wide toe box lets your forefoot splay fully — reduces hotspots and builds the foot strength minimalist running is all about
• Available in Obsidian — sized EU 47 (US 13) and EU 49 (US 15) for larger feet that most minimalist brands ignore
