The Primus Flow is the newest member of the Primus family, designed for pinnacle barefoot running performance. Built for efficient and unrestricted natural movement, this ultra-lightweight runner – our lightest ever – weighs in at just 150g. Its lightweight, breathable upper made from engineered recycled mesh forgoes overlays in favour of a stripped-back, seamless construction.
Features
- PRIMUS FLOW OUTSOLE — Reconnect and run slow
- NO INSOLE — No insole, bringing you even closer to the ground for a greater barefoot experience.
- BREATHABLE MESH — Breathable, lightweight and comfortable.
- 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.
- LACES 100% recycled polyester
