Primus Knit FG Running Shoe – Men's

For runners shifting to natural movement on dirt and technical terrain, the Primus Trail Knit FG is our go-to barefoot trail shoe for building foot strength and ground feel. The thin, puncture-resistant FG sole lets you read roots and rocks, while the breathable knit upper keeps your feet cooler through Southern humidity.

• Zero-drop platform puts your foot in a natural position and works the small stabilizing muscles that cushioned shoes let sit idle
• Thin, puncture-resistant firm-ground outsole gives you raw trail feedback while still guarding against sharp rocks and roots
• Breathable knit upper flexes with your foot and vents heat, so humid summer miles stay manageable
• Wide, foot-shaped toe box lets your toes splay for better balance and comfort on long days. Sizes run EU 43–48
• Light and packable enough to double as a camp shoe or hike-in approach shoe. Choose from Obsidian, Storm Cloud, Purple Heather, Peyote, and more
