Crocs Kids Sandals M2W4, about 22cm Although they are kids' sandals, adults with small feet can also wear them. I usually wear size 23cm shoes and used these as a snug fit. Purchased a while ago at a Crocs official store in Hawaii. They have some signs of wear, so please only purchase if you understand this. Shipping method is as follows: Non-standard mail (regular mail) Shipping will be on weekdays. If you would like a tracking number or anonymous shipping, please comment before purchasing, and I can accommodate for an additional 200 yen. They will be wrapped in bubble wrap and shipped in a paper bag or plastic bag. No need to comment, you can purchase directly.
