Overview: Trail Grip Plus a Conductive Path to the Ground

The Vivobarefoot Primus Trail Knit FG Grounding Womens is the knit trail runner with conductive grounding built in. Conductive material in the firm-ground outsole and the removable insole creates a pathway between your body and the earth — connection to the ground that's electrical as well as sensory, in a shoe that still grips real trails.

• Conductive outsole and insole: An electron pathway to the earth for grounding (earthing) on natural surfaces — soil, grass, sand and rock.
• Firm-ground outsole, 4 mm lugs: Traction on mixed terrain without deadening the trail beneath you.
• 3 mm sole, zero drop: Thin enough for genuine ground feel; level heel-to-toe for natural gait over uneven ground.
• Wide toe box: Toes splay for balance and stability, especially on descents.
• 81% recycled polyester knit upper, vegan: Light, breathable and fast-drying.

How Does It Compare?

It's the Primus Trail Knit FG Womens with conductive materials added — choose the standard model if grounding isn't a priority. For softer, muddier ground see the Primus Trail III SG Womens; for gym and road, the Primus Lite IV Womens.

True to size, with give in the knit upper and a deliberately roomy forefoot. Colourways: Eclipse Purple Heather and Wood.

Pros & Cons

Pros: unique conductive grounding build, genuine trail grip with ground feel, light and quick-drying, vegan recycled upper.

Frequently Asked Questions

What does "Grounding" mean on this shoe?

Conductive material runs through the outsole and insole, creating a conductive pathway between your foot and the ground. On natural surfaces that allows the earthing effect you'd otherwise only get walking barefoot. Health claims around grounding remain scientifically debated — the shoe's trail performance stands on its own.

What terrain is it best for?

Trail running, fastpacking and hiking on mixed natural terrain. Deep mud is better served by a soft-ground model.

Is it suitable for barefoot beginners?

Better once you have some barefoot mileage. A thin sole on uneven terrain asks a lot of unadapted feet — start easy and build gradually.
