Vivobarefoot Primus Trail FG 3.5 - Obsidian
Description
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.
Fit, Feel, Flex: For natural stability, natural sensory feedback and natural strength.
