These are stunning booties, size European 41, which will be an ideal fit for someone US size 10, I do not recommend these shoes for someone with a wide foot, regular or narrow width would be perfect! I am true to size 10, that’s my foot. I’ll be listing these as a size 9.5-10, please read description and know your designer’s size as I do not accept returns. Shoes run different from Poshmark size chart. These are in amazing condition, professionally added sole protectors , come with a dust bag. Beauties! These are gorgeous!!! Authentic!!!
