Oceania avocado Merrell slip on size 8. But fits a bit small.

I'm reposting this item as it unfortunately doesn't fit me. It says a size 8 but I think they are more a size 7.5 US woman. I'm normally a size 6 UK. On the tag is mentions 5.5 UK These shoes are in great condition, and look super comfy. I wished they fit me but I guess I'm no Cinderella.
