The Primus Trail Knit FG Grounding does everything great trail footwear should. Designed for natural movement on mixed terrain, its thin Firm Ground sole balances grip with barefoot sensation, helping you build strength while staying connected to the trail. A breathable knit upper allows feet to move freely while helping keep debris out. Built with grounding conductive materials, it offers an even more direct connection to the ground for those seeking a deeper barefoot experience. Conductive Firm Ground outsole Trail-ready. Earth-connected. Conductive insole The removable conductive insole creates a pathway between your body and the earth beneath you - so every step feels like more than just movement. VEGAN* *The main materials in all our Vegan* products are synthetic and aren&';t derived from animals. We don&';t (yet) have the transparency we need over the production of all the small components (such as adhesives and dyes) used in these products to ensure they meet vegan best practices. So, whilst we believe the shoes are vegan, we&';re not yet able to guarantee it and want to be fully transparent. Care Cleaning Clean with a slightly damp, soapy cloth. Drying Remove insole and dry at room temperature. Keep out of direct sunlight and avoid intense heat source. Aftercare With wear, your shoes may loose some water resistent quality that is applied to the textile of the shoes. Vivobarefoot Repel: Protector can be used to replenish the water repellent qualities.
