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.
Product information
Firm Ground Outsole
Stand firm on multiple terrains.
Vivos are designed with thin soles to help reconnect you with the ground, and provide flexibility for strong, healthy feet.
2.5mm
Tread depth refers to the thickness of the patterns or “lugs,” on the sole. These are purposefully designed to cater to specific surfaces and conditions, providing an ideal combination of traction, grip, and a sense of connection with the ground.
The Firm Ground outsole is made of a sticky rubber compound that provides excellent grip and durability. With a 3mm base and 2.5mm lug height, plus a textured arch for zonal grip (ideal for technical trail movement), this sole will keep your feet firmly planted on multiple terrains – wet to dry, concrete to rocky.
Welcome back the wild.
Human beings aren’t separate to nature, we are nature. When we listen to its rhythm and connect to its intelligence, we thrive. It’s time to get outside and rewild.
Ortholite Insole
The Ortholite Performance Insole is made of 98% recycled polyurethane foam, which helps reduce waste and the use of virgin plastics.
Tough Rubber Compound
Strong, non-marking rubber compound for sticky grip and high-abrasion when you need it most.
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.
