Primus III All Weather SG Running Shoe – Men's

Built for wet, gnarly terrain where most barefoot shoes tap out, the Primus Trail III All Weather SG is our pick for trail runners who refuse to give up ground feel when conditions get ugly. A soft ground lug outsole bites into mud and loose dirt, while the all-weather upper keeps feet protected without killing proprioceptive feedback.

• Soft ground (SG) lug configuration digs into mud, wet roots, and loose trail surfaces for reliable grip when conditions deteriorate
• All-weather upper construction sheds moisture and resists the elements without sacrificing the breathability barefoot runners depend on
• Wide toe box and zero-drop platform let your foot splay and load naturally — no heel lift, no compressed toes, no compromises
• Thin, puncture-resistant sole keeps ground feel intact on technical terrain, so your feet actually work the way they're built to
• Available in Obsidian — a low-profile colorway that works from the trail to the trailhead without looking like a science experiment
