Grounded Performance for Every Adventure

Discover a new way to experience the trail with the Vivobarefoot Primus Trail Knit FG Grounded. This lightweight barefoot trail shoe combines the freedom of natural movement with innovative grounding technology, making it ideal for trail running, hiking, fastpacking, outdoor adventure, and everyday exploration.

An evolution of the iconic Primus Trail FG, this latest model features a breathable recycled-knit upper, a responsive Firm Ground outsole, and conductive technology designed to support grounding when worn on suitable natural surfaces. Whether you're navigating mountain trails, coastal paths, or forest tracks, the Primus Trail Knit FG Grounded helps you move naturally while staying connected to the terrain beneath your feet.

Built for Natural Movement

Your feet were designed to move freely.

The Primus Trail Knit FG Grounded features Vivobarefoot's signature barefoot design, including a wide toe box, thin flexible sole, and zero-drop platform. Together, these elements allow your feet to spread, flex, and stabilise naturally while providing exceptional ground feel and sensory feedback.

Rather than restricting movement, this shoe encourages stronger, healthier foot function with every step.

What Is Grounding?

Grounding, also known as earthing, is the practice of connecting with the Earth's natural surface.

Traditionally, this happens by walking barefoot on grass, soil, sand, or rock. The Primus Trail Knit FG Grounded has been developed to help support this connection through conductive technology integrated into the outsole, silver conductive thread, and the Grounding OrthoLite® insole.

When used on suitable natural conductive surfaces, the shoe is designed to help maintain a connection between your body and the Earth while still providing the protection and grip needed for outdoor adventures.

Why Choose a Grounding Trail Shoe?

Modern life often separates us from the natural world.

The Primus Trail Knit FG Grounded encourages you to spend more time outdoors while embracing natural movement. Many people who practise grounding describe feeling more connected to nature, more present during outdoor activities, and increasingly aware of the terrain beneath their feet.

While scientific research into grounding continues to develop, regular movement outdoors and time spent in nature are widely recognised as important contributors to overall physical and mental wellbeing.
