Little boys Crocs slip ons

little boys gently used Crocs slip ons, when I purchased these there was no tag for the size so see shoe sizing chart on the picture I have posted, when I bought them my son was between a 7-8 little kids, no flaws at all, the brown marks on the bottom are from the previous sale sticker that was in there, no wear at tear at all on these shoes, tons of life left any questions please feel free to ask Thanks
