I've tried them previously. They are very soft leather and look beautiful. I would have bought my regular size, 6.5. They're not too narrow (their other shoes tend to be very narrow, but not these).
Imperfections for my feet: slightly low volume for my high volume feet -- they dug into the top of my foot a tiny bit, which is almost inevitable for me, more than most people. The elastic at the back of the shoe was a little bunchy and didn't seem like it would be the best on my foot shape. If I'd been looking for something like them they would have been a contender, but not perfect for me.
Honestly, I've never been able to buy shoes without returning most options... shoes might just be something you have to either try on in stores or be willing to return. Or maybe I'm just unlucky!
