The Primus Trail Knit FG Grounding does everything great trail footwear should. Designed for natural movement on mixed terrain, its thin Firm Ground sole balances grip with barefoot sensation, helping you build strength while staying connected to the trail. A breathable knit upper allows feet to move freely while helping keep debris out. Built with grounding conductive materials, it offers an even more direct connection to the ground for those seeking a deeper barefoot experience.

The trail runner that brings you closer to earth

Conductive Firm Ground outsole

Trail-ready. Earth-connected.

3mm

Vivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.

4mm

Tread depth refers to the thickness of the patterns or "lugs," on the sole. These are purposefully designed to cater to specific surfaces and conditions, providing an ideal combination of traction, grip, and a sense of connection with the ground.

Feel the trail and the earth beneath it. The Conductive Firm Ground outsole combines grip, traction and barefoot sensation with conductive elements that create a pathway for electrons to flow between your body and the Earth's surface.

Deepen your connection

Vivos give your feet a chance to feel and the freedom to move, so you can connect to nature and to yourself. Conductive barefootwear enables you to connect on a deeper level – by keeping you in harmony with the natural world, and even closer to your human potential.

Conductive insole

The removable conductive insole creates a pathway between your body and the earth beneath you – so every step feels like more than just movement.

VEGAN*

*The main materials in all our Vegan* products are synthetic and aren’t derived from animals. We don’t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we’re not yet able to guarantee it and want to be fully transparent.
