Vivobarefoot Size Chart

Vivobarefoot Size Chart

Find your perfect fit. Our shoes fit "big" deliberately — your toes need room to spread and move naturally. All measurements below are foot length, not shoe length.

The Rule of Thumb If you can fit your thumb between the end of your longest toe and the front of the shoe, you have more than likely found your ideal size. This is especially important for running.

Women's Footwear

Measure your feet at the end of the day, when they are at their largest. Add 6–14 mm of toe allowance to the foot length below.

How to Measure Your Foot

  1. Stand on a piece of paper on a hard, flat floor with your heel against a wall.
  2. With your full weight on the foot, mark the tip of your longest toe with a pencil.
  3. Measure the distance from the wall to the mark. Measure both feet and use the larger measurement.
  4. Add 6–14 mm for toe allowance, then match your measurement to the chart above.

Fit Tips

Narrow Feet / Snug Fit If your measurement sits at the top of the 6–14 mm allowance and you have narrow feet, you may prefer to size down. We still recommend at least 4 mm of toe room.
Wide Feet / Loose Fit If you have wide feet or prefer a roomier fit, you may want more than 14 mm of space at the front. Many customers happily wear up to 20 mm.
Crossover Sizes (EU 40–43) Men with narrower feet may prefer the women's fit, and women with wider feet may prefer the men's fit. This is very common.
Your Feet May Change Barefoot footwear lets toes spread naturally, so your size may need to increase over time as your feet strengthen and splay.

The Science

  • Kids' feet grow between 5 mm and 11 mm per year between the ages of 6 and 16.
  • Teenagers' and adults' feet can grow up to a size (7–8 mm or more) after exercise or over the course of a day.
  • Adults' feet can keep growing by up to half a size per decade, even after 40.
  • This is why our fit recommendations include 6–14 mm of toe room for growth, daily movement and styling.
Measurements are foot length in centimetres. Sizing may vary slightly between styles — always check the individual product page for style-specific advice.
