Vivobarefoot Primus Trail Knit FG Grounding Mens Obsidian/Obsidian
A trail runner that does much more, the vegan* Primus Trail Knit FG also now evolves this iconic shoe to enable the practice of grounding. When worn on natural surfaces, silver conductive thread and new grounding technology in the footbed help connect you to the natural energy of the trail. The thin, Firm Ground sole balances barefoot sensation with grip, and also helps build your foot s natural strength while moving. And the knit upper and conductive insock keep you comfy as you go, blocking trail debris and ensuring breathability.
