These are listed as size 11 on the shoe but I find that these sandals run large so I have them listed above. They are adjustable of course but I feel like they would fit up to a size 13. My child is a 12 and her foot is a little narrow but there is lots of room to spare. Would be great for kiddos with wide feet. If you would like to see them on her foot, I will be happy to take pictures! NWOT
