| Foot Length (cm) | EU | UK | US |
|---|---|---|---|
| 26.2 | 40 | 6 | 7 |
| 26.9 | 41 | 7 | 8 |

The Rule of Thumb
Vivobarefoot deliberately fits larger—your toes need room to splay naturally. If you can fit your thumb between your longest toe and the shoe’s front, you're likely wearing the right size. Over time, as toes spread, you may need to move up a size.
How to Measure Your Feet
- Stand on a hard surface with your heel against a wall.
- Mark the tip of your longest toe and measure to the wall in cm.
- Use the measurement above to choose the corresponding EU/UK/US size.
- Measure both feet and use the longer measurement.
Sizing Tips & Returns
- Vivobarefoot shoes run larger than traditional footwear—don’t worry, this supports natural toe splay.
- If you’re between sizes, we recommend sizing up for comfort rather than over-tight fit.
- Changed your mind? Return unused shoes within 365 days for a full refund or store credit—no questions asked.

WHY GO BAREFOOT
Wearing Vivos for 6 months increases foot strength by 60%
Better Balance and Posture
Foot-shaped fit enables toes to splay supporting balance and a stable base of support.
Improved Coordination And Agility
Thin sole allows the thousands of nerve endings in each foot enabling the sensory feedback the brain needs to move with skill.
Improved Strength and Natural Movement
Flexible footwear let the muscles and tendons load and recoil, supporting stronger, more resilient feet over time.
