Hit the trail to rewild yourself and reconnect with nature. The Primus Trail 3.5 FG is a light, durable, flexible trail-running trainer that brings us one step closer to circular footwear.
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.
Vivobarefoot is on a mission to create a fully circular shoe - a new Vivio 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, of which 93% is recycled. Why not 100% Because some parts of the upper still need extra durability that polyester can't yet provide. Vivobarefoot is working with their partners to figure out this final piece of the puzzle.
Details:
- Foot shaped (not shoe shaped), to let your feet do their natural thing
- WIDE to allow for natural stability
- THIN to enable you to feel more
- FLEXIBLE to enable natural movement.
- Cleaning: Brush off mud and clean with a damp cloth
- Drying: Remove insole and dry at room temperature, keep out of direct sunlight and avoid putting near any heating element
- FIRM GROUND OUTSOLE: The Firm Ground Outsole is made from a sticky rubber compound for maximum grip and durability. With a 3mm sole base and 2.5mm lug height, plus a textured arch for zonal grip (ideal for technical trail movement), this sole will keep your feet firmly planted on multiple terrains - wet to dry, concrete to rocky.
- ORTHOLITE INSOLE: The Active Ortholite Performance insole is made of 98% recycled PU foam, which helps reduce waste and the use of virgin plastics.
