The Vivobarefoot Primus Trail Flow Dark Shadow is designed for trail running, fast hiking and everyday outdoor movement, following true barefoot principles. Its upper is made from recycled polyester mesh with TPU overlays, offering breathability, durability and water resistance while remaining vegan-friendly.
The Trail Flow outsole provides reliable traction on wet, dry and uneven surfaces while maintaining flexibility and close contact with the ground. The wide toe box allows natural toe splay, and the zero-drop sole supports natural posture and balance.
Designed without a traditional insole, this model maximises sensory feedback and ground feel. Light, responsive and versatile, the Primus Trail Flow is ideal for active outdoor use and natural movement on all types of terrain.
