Vivobarefoot Primus Trail Flow Mid - Women

The freedom to feel the ground with extra protection

When the terrain gets rough or the weather turns cold, the Primus Trail Flow Mid keeps the barefoot essence with added coverage. Its mid-cut collar hugs your ankle without restricting movement, giving you extra security without losing lightness or ground feel.

It’s the natural evolution of the low version: same connection to the ground, same immediate feedback, but with a more supportive and stable fit. Ideal for long routes, cool trails, or when you want a barefoot shoe with a little more support.

The barefoot that protects without isolating you

Its thin and flexible sole keeps you connected to the terrain, while the elastic mid collar provides support and comfort around the ankle. The wide toe box lets your toes move freely and stabilize every step, and the zero drop ensures a natural, aligned posture.

The light and durable ripstop fabric adds breathability and quick drying, making it perfect for alternating between wet and dusty trails. Altogether, it strikes a balance between freedom, protection, and control.

Recommended use

Moderate trail running, light trekking, and mixed routes with elevation. Also perfect for autumn or winter when you want a versatile barefoot shoe that offers a bit more protection from cold or rough ground.

Why you’ll love it

Because it lets you feel the terrain without giving up security. Its mid-cut fit supports every turn, the sole responds instantly, and the feeling of control is total. It connects you with nature—without overexposing you.

Opinion

It doesn’t try to impress; it just works with you. The Primus Trail Flow Mid gives you confidence and precision with every step. It’s the perfect middle ground between total freedom and the protection you need to keep flowing even when the path gets tougher.

Care and maintenance

Remove dirt with a soft brush after each use. Hand wash with cold water and mild soap if necessary. Air dry away from direct heat sources. Do not machine wash or tumble dry. To extend sole life, avoid abrasive surfaces when not needed.
