Ok, to the reviewer who wrote this is not a boot with a wide shaft I say either 1. you have ginormous calves and should just stick to ankle boots,or 2. you accidentally bouugh the regular ones.  This is IN FACT 100% the wide shaft boot, how do I know you ask? I, thinking I had regular size calves, bought the regular boots from DSW, sadly there was about an inch of space between the two sides of the zipper when I tried zipping them up...tres dissapointing. So I found the wide shaft version on Amazon and they fit perfectly with some room left over. So, this is exactly the 16 1/2 shaft that they promised so if anyone is concerned with buying because they think they are getting the wrong boot, please don't be. On a separate note, its a nice boot, cant speak to the quality of the zipper (which seems to be an issue in quite a few reviews that i read) because i only had them for one day and haven't even worn them out. They are perfect with skinny jeans on a rainy (or not) day. Very nice, very elegant shoe, highly recommend!
