I really, really wanted to love this shoe. When it came the first time in my usual size 6, I was bummed that it was weirdly large (like at least 1 whole size up). But I saw that they actually sell it in a 5.5, so I thought I'd give it a second chance and hope that the smaller size would fit like my normal 6. Welp, it definitely didn't. Still about the size of a 7. And what's weirder is that the 2 sides (left vs. right) were off in their fit. The left shoe was much tighter than the right, which makes me think that I was sent a pair that was used as a try-on sample from one of the stores. That's not always the worst, but when it makes the two sides of a pair completely different fits (on top of already being a larger-than-normal show), it just isn't going to work. And this shoe does have any way to be tightened. The back has a zipper and the front straps aren't adjustable.
Sorry this was a long review, but I hope I can help someone else who might be considering this purchase. If you really want it, be prepared to try a few different sizes to find the right one.

I ordered this is a Size 6 and when it came, it not only fit too big, I could tell just by looking that it was way too large. Not sure how the shoe sizing works, but it's at least a half-size or possibly even one whole shoe size up. I've asked for a return and am debating on exchanging for the 5.5 size to see if that will fit like a normal 6. If you're going to order, just be aware that you surprisingly need to size down or may even have to return/exchange, as there is no way to adjust if it's too big due to the design of the shoe. I don't know if this applies to all sizes, but I'd at least assume so. Other than the weird sizing, the shoe itself is super cute and seemed comfortable. I didn't get to walk around in it because mine were too big, but the material on the sole seems very comfortable.
