Primus FG 3.5 Running Shoe – Women's

For trail runners ready to move toward barefoot-style running on technical terrain, the Primus Trail FG 3.5 is our go-to running shoe. A thin, puncture-resistant sole gives you real ground feel without exposing your feet to sharp debris, while the wide toe box lets your toes splay naturally on long descents.

• Thin puncture-resistant sole gives you true ground feedback while still shielding your feet from sharp rocks and roots
• Firm-ground outsole bites into hardpack, roots, and technical surfaces common on Southern Appalachian and Gulf Coast trails
• Wide toe box allows natural toe splay for better balance, grip, and comfort over long miles, with no toe squish on descents
• Lightweight, low-profile build suits runners transitioning to minimalist footwear or already training in it
• Comes in Insignia Blue, Obsidian, and Mineral, in EU 37 to EU 42 (US 7 to 11)
