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.

All-weather sneakers for speedy hardpack trail adventures
A true barefoot trail runner for cooler, wetter conditions, the Primus Trail III AW FG also excels at fast hiking, fastpacking and other speedy, hardpack trail adventures. It’s also popular for rainy, outdoor-forward city living.
It’s wide, thin and flexible for full feeling and natural mobility on uneven ground. The quick-lace system allows for fast on-off and easy adjustments. And the Firm Ground sole balances sensitivity, grip and speed on varied hardpack terrain, building natural strength with every step.
