I work in an office and it's warm here in Florida. My old clogs aren't always professional-looking, but these sandals are really cute and fit well. They were a little tight and stiff across the instep for a while, but they're loosening up. The size is perfect. I was worried about ordering them and put it off for a long time because of some previous reviews. Now I wish I'd ordered a pair in every color!
I have worn the same size shoe for years - 39M - but this one wasn't even close. And costly to return for a mis-sized product after paying for shipping both ways.
These looked good and were a great price on sale, but were way too narrow for my feet. I'm sure they would stretch some, but not enough. I had to return them.
