I can say these run true to size.  I wear anywhere between a 6 and a 7 depending on the shoe type, so I got a 6.5 and it fits perfectly.  I like them and they seem really comfy, in fact I just got them and I am wearing them as I type this.  The only complaint I have is that the leather feels a bit stiff.  I am short and the ankle part goes higher on me than it probably would for most people ( 4'11") but it is not so uncomfortable that I would return them.  Despite that they seem of a nice quality and they have a nice look to them. I would think these would also be comfortable to someone with a wide foot as since you can adjust how wide they go by simply loosening the laces.  Even some people who can't wear sandals due to ankle problems should be fine with these as well since they provide a lot of stability due to their stiffness in the ankle area.  It's like the perfect combination of a ankle boot and a sandal.  I will say they feel a bit strange but I think I will get used to them.  They are too cute to give up on.

**update 8.16.18: I can say that they have softened up in the heel so now they don't rub and cause sores, and not only are they still super cute but they have held up quite nicely.  I will certainly be getting another pair to keep in my closet when these wear out since I practically live in them.  Also for people that have wide feet, I had my mum try them on (she has a bad bunion) and she said they were really comfortable because you can adjust the size to fit your foot.  This is seriously an awesome shoe especially for the price.
