Run wild, whatever the elements
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.
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.
Our Size Guide is here to help! Vivobarefoot fit 'big' deliberately – we call this ‘the rule of thumb’. Your toes need wiggle room! This is especially important for running. If you can fit your thumb in-between the end of your toe and the front of the shoe, you’ve more than likely found your ideal size.
**After some time with Vivobarefoot shoes, your shoe size may need to increase, as your toes splay out more naturally.**
