🌻NWOT Size 11M Sketchers Sandals

So my sister has big feel like me (she thinks), but mine are bigger. And she thinks that if she doesn’t like them they will surely fit me…and they did when I was 13 years old before I earned my size 12 hooves! She ditched the box, but these are an 11…like every other 11 she wears. She just didn’t like them. I can’t find a size on them anywhere though.
