Size M (25 cm) Sawatabi (Japanese water shoes) Perfect for streams, creeks, and water play! I used these with thick socks, and my shoe size is 26 cm. I cannot ship from November 3rd to 20th. These are used items, so there may be minor stains or differences in how they feel. The product photos may look different from the actual color due to your smartphone model or lighting during photography. Please ask any questions you may have until you are satisfied. Please purchase only if you understand this. I will only conduct transactions with those who will not cancel their purchase, have common sense, and understand that these are used items. Please refrain from purchasing if you are overly concerned about minor details.
