These shoes are super cute, and super comfy.  I got the midnight ones expecting them to be black, but they are actually a dark blue.  There is a zipper in the back, but it is easier to undo the top strap (which closes with Velcro) than to deal with the zipper each time.  Plenty of cushion, and straps are not binding.  I usually wear size 7.5-8, and bought the 8.  Have plenty of room without being too big.
