The Primus Trail 3.5 FG is for runners who live for the end of the road. These all-terrain trainers are light and flexible enough to move freely, and tough enough to run wild on rough, rocky ground. Made with recycled, vegan*, high-performance materials.
Fit, Feel, Flex
For natural stability, natural sensory feedback and natural strength.
Firm Ground Outsole
The Firm Ground Outsole is made from a sticky rubber compound for maximum 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 it's rhythm and connect to its intelligence, we thrive. It's time to get outside and rewild.
