Run free, run wild
Perfect for speedy hardpack trail adventures
First and foremost a trail runner, the Primus Trail II FG also excels at fastpacking and hiking. Its low profile even makes it popular for outdoor-forward city lifestyles, including HIIT workouts and strength training.
The wide, thin, flexible build offers supreme sensitivity 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.**
