I train in one of the martial arts where Tabi is often used. I am about to order a pair of leather Tabi and have a question regarding measurement.
The International Shoe Size Conversion Charts Table from www.i18nguy.com/l10n/shoes.html looks like this:

- Why is there a difference between Centimeters and Japan(M)? I thought you measured, in centimeters, from the heel to the end of the longest toe and that it was you size according to the japanese shoe size convention. And if that is correct, I would assume that these rows would line up perfectly.
The actual vendor I am thinking about ordering from has this conversion table at www.leathertabi.net/footsizechart.html:

- It does not match up with the previous conversion table. Any thoughts on that?
- What is the correct way to measure the foot and converting it to the japanese shoe size system?
