!! Please be sure to read the profile before purchasing to prevent any issues !! I cut the tags off intending to use them, but they were already too small. Unused, I'll include the cut tags. Made with Imabari fabric, which is gentle on the skin. The size is probably up to ~12cm. They didn't fit when I tried them on, and I usually wear 13.5cm shoes. How about them for first shoes, room shoes, or pre-shoes?
