My struggle has been that as a fat person I have wide ankles, but that doesnt automatically mean I have wide feet. Shoes made for wide feet don't work for me, but regular width shoes with ankle straps don't accommodate my ankles. This problem has been plaguing me in my search for good water shoes. Even Chacos didn't work for me because I happen to have small feet at the end of big legs. :( These are the only ones I found that worked. Im a size 8 (not exactly small but average), but the size 8 didn't work. Size 9 is not so terribly long that I cant manage it. The ankle strap doesnt close as much as I would like, unfortunately, but other than a bit of unattractive visible Velcro, it looks great.  More importantly, it *feels* great. Comfortable out of the box, I can walk in them all day. I haven't tested them in water yet, but based on how they did when my feet got sweaty, I will guess they don't disappoint. My sweaty feet did not slip. The adjustable straps over the front probably have a lot to do with that. They allow for more precision than some offerings out there.
