These are just the boots I was looking for. I'm a big Crocs brand fan because they actually have my size (womens 4).
I had read a review that said they were snug to get on. That wasn't the half of it! I have a high arch, but not extraordinarily so. I nearly sprained an ankle trying to get the first boot on. The second was even harder, and getting them off was more difficult still. To top it off, once they were on, they felt large on my feet. They probably would have been perfect with socks (I tried them on with just tights), but there is no way that I would have been able to get them on at all wearing socks.
I'm terribly disappointed that I had to return these.
I rated them a 3, because they were attractive and well-made (perhaps the zipper could have gone lower for easier entry?). If you don't have a high arch, they could be the boots for you.
