I just got the slides delivered this morning and sadly put them in my return pile. They do fit a good 1/2 size small. Being backless, that wouldn't have caused a huge issue, especially since I wear an 11, so going up a size wasn't possible. The deal-breaker for me was that as I walked around the house, my foot felt like it was 'sloshing around' inside the shoe, which surprised me since I have a wide foot. This movement caused my heel to overhang more, as I felt like I was struggling to keep my foot inside the shoe.
Disappointing, as I've been wanting a leopard flat of some sort for a while, but not meant to be with these. I used to have a pair of leopard print smoking shoes that I wore to death and would love to have a fun, printed shoe back in rotation! If you can find the right size for you, these are still a very cute shoe in person.
