Run and roam wild
Built for trail running and adventuring closer to nature
The Primus Trail 3.5 FG is for runners who live for the end of the road. These all-terrain trainers are light and flexible enough to move freely, and tough enough to run wild on rough, rocky ground. Made with recycled, vegan*, high-performance materials.
We're on a mission to create a fully circular shoe – a new Vivo made from an old one, which can in turn be made into another. The Primus 3.5 is a big step forward on this journey.

With an already mechanically recyclable outsole, the challenge is making an upper from 100% polyester, which can be recycled. The new Primus Trail 3.5 upper takes us from 34% to 76% polyester, of which 93% is recycled. Why not 100%? Because some parts of the upper still need extra durability that polyester can't yet provide. We’re working with our partners to figure out this final piece of the puzzle.
Multi-terrain: Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.
Urban: Stripped-back soles for barefoot living — so you're never too far from nature, even in the city.
Fit, Feel, Flex: For natural stability, natural sensory feedback and natural strength.
WHY VIVOBAREFOOT IS DIFFERENT
Vivobarefoot shoes are designed to let your feet move naturally. With a wide toe box, thin flexible sole, and zero-drop platform, they allow your feet to function the way they were designed to. Traditional shoes often add cushioning and structure that can reduce natural movement and sensory feedback.
| Feature | Vivobarefoot | Traditional Shoes |
|---|---|---|
| Toe Box | Wide and foot-shaped for natural toe splay | Narrow and tapered |
| Sole | Thin and flexible for ground feel | Thick and cushioned |
| Heel Drop | Zero drop for natural posture | Raised heel alters posture |
| Movement | Encourages natural foot strength and mobility | Supports and restricts natural movement |
| Purpose | Designed to reconnect you with natural movement | Designed mainly for cushioning and control |
