Size L, which according to Innocent World's sizing is 24.5cm. That's also my size and they fit comfortably. I tried them on but decided the style isn't for me. There is some rubbing on the strap at the back where it goes through the back loop (see photo 4). I think this could be easily sealed off to stop any further rubbing. The soles look they have been worn 1 - 2 times. There's no other damage that I can see.
