I purchased a pair of zori (sandals) and tabi (socks) for a 7-year-old from Rakuten. They were worn once on a sunny day. The tabi are labeled as 19-20 cm. The zori are 21 cm, and they fit perfectly. The white tabi have faint brown marks on the heels and the back sides (photos 3 and 4). It's difficult to see, but please check the photos. Please understand that these are used items before purchasing.
