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.

The "Rule of Thumb" Fit Tip
Vivobarefoot intentionally fits larger to give your toes room to wiggle—especially important for natural movement. If you can comfortably fit your thumb between your longest toe and the shoe’s front, you’ve likely found the right size. Over time, as your toes naturally splay, you may need to go up a size.
How to Measure Your Feet
- Stand with your heel against a wall on a hard surface and measure from wall to tip of your longest toe in centimeters.
- Use the “cm” column above to determine your size.
- Measure both feet and base your choice on the larger measurement.
- Measure at the end of the day when your feet are slightly larger.
Sizing Advice & Return Policy
- Vivobarefoot fits liberally—don’t size down to compensate. A bit more room means better barefoot feel.
- If you're between sizes or plan to wear thick socks, consider sizing up for lasting comfort.
- Not completely sure? You have a full 365 days to return unused shoes for a refund or store credit—stress-free returns.
