What size fits me?
Barefoot shoes need space for your toes to spread — but not so much that your foot slides. Measure at home, then always use the inner-length chart on that product. Brands do not share one last.
Toe room
10–12 mm
In front of your longest toe, standing

Use the mm
Go up if the smaller size leaves under 8 mm

How to measure
Do this in the afternoon, standing, with the socks you would actually wear. Sitting shortens the foot.
- 1
Put a sheet of paper against a wall. Heel to the wall, full weight on the foot.
- 2
Mark the tip of your longest toe (it is not always the big toe) and the back of the heel.
- 3
Measure that length in millimetres or centimetres. Repeat for the other foot and use the longer one.
- 4
Compare with the inner-length chart on the product page — not with a pair of ordinary sneakers you already own. Add 10–12 mm to your foot length and pick the size whose inner length matches that number.
How they should feel
- Aim for about 10–12 mm in front of the longest toe in a closed shoe. Under 8 mm is usually too short; much over 15 mm and the shoe can slip.
- Snug at the heel, never tight across the ball or toes. Width is the deal-breaker — if toes press the sides, go wider or up a size.
- Sandals can sit a little shorter because the toe is open. Winter boots with thick socks can take a few millimetres more.
- Kids need extra growth room — closer to 12–15 mm. Re-measure often and replace when there is under about 10 mm left.
Every brand is a little different
Vivo, Be Lenka, Groundies, Affenzahn and the rest do not share one last. The only chart that matters is the one on that product. If a pair is marked as running long or short, trust that note over a generic EU size.
If it is not right
