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.

Fast, versatile hardpack adventures outdoors
Trail runners that do much more
Made for trail running, the Primus Trail Knit FG is also excellent for fastpacking and hiking. Its low profile and versatility also makes it a popular choice of outdoor lovers wherever they tread.
A knit upper and sock bring flexibility and protection. A quick-lace system means easy adjustments. And a thin Firm Ground sole balances barefoot sensation with grip, feeling fast on varied hardpack terrain, building natural strength with every step.
multi-terrain
Giving you grip and ground feel on everything from wet and dry, rocky and firm terrain.
Urban
Stripped-back soles for barefoot living — so you're never too far from nature, even in the city.
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.
