The Primus Trail III All Weather Firm Ground is a water-resistant evolution of the Primus Trail FG: our original, best-selling trail-running sneaker.
Similarly light, durable and flexible for varied hardpack trail adventures – made with recycled, vegan*, high-performance materials – the Primus Trail III AW FG features water-resistant materials for trail runs and hikes in wetter, cooler climes.

Stand firm on multiple terrains.

The Ortholite Performance Insole is made of 98% recycled polyurethane foam, which helps reduce waste and the use of virgin plastics.

Strong, non-marking rubber compound for sticky grip and high-abrasion when you need it most.

*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.

Made using water-resistant constructions and non-absorbent materials.

Made from materials that are water resistant and materials that are non-absorbent.

Based on a single shoe in Men's size: EU 42 | UK 8 | US 9
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
