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.
