I wear a 7.5 in most all shoes- except for naturalizer. Since they always run big I size down to a 7. And that was true for these sandals. I like them a lot, cute style, comfortable low heel rather than flat, and soft cushioned foot bed that feels like suede. However, the top strap is too far back on the shoe and rubs the front of my ankle. So I can't wear them for long or for much walking. But since I got them on sale I'm keeping them for nice bedroom slippers.
