Sizing
Our shoes are unisex and fit true to size, although they may feel spacious if you've not worn barefoot shoes before.
If you're between sizes, we recommend sizing down.
For greater certainty, we recommend measuring your feet:
- Put a piece of paper on the floor flush up against a wall.
- Place one foot on the paper with your heel right up against the wall.
- Use a hardback book on its side as a straight-edge to find the longest part of your foot. Mark this point with a pencil.
- Use a ruler or tape measure to find the straight-line distance from the edge of the paper to your pencil marking.
- Repeat with the other foot and find the size below that corresponds to the measurement of your longer foot.

If you've not worn barefoot shoes before, you may find nackt shoes a bit roomier than you're used to. We hope that you enjoy the freedom that this extra space affords.
