Vivobarefoot Primus Trail Flow - Mens Trail Running Shoes

Move naturally, wherever the trail takes you. The new Primus Trail Flow is a lightweight, barefoot-inspired trail shoe designed to connect you to the ground with precision and confidence. Its streamlined silhouette combines durable performance with natural movement, delivering grip, protection, and freedom in every step.

The breathable mesh upper, made from 100% recycled polyester, keeps your feet cool and secure with anti-slip engineered lacing. Underfoot, a flexible ETPU midsole cushions without dulling sensory feedback, while the All Terrain outsole balances protection with grip. With a 1.8mm base and optimised 3.5mm lugs, you’ll feel every nuance of the ground beneath you, without trail debris getting in the way.
