I ordered these boots because they looked shorter and wider at the top than most rain boots. I have very wide ankles and calves. These boots fit great right out of the box! I ordered my normal shoe size and liked the fit. My main complaint is that after leaving them in the car for a day in warm weather, they shrunk! I was still able to put them on, but they felt a little snug. At the time I thought maybe I was wearing different socks that were thicker so I didn't think anything of it. A couple days later (they were still in the car), I couldn't even get them on my feet. Being in the hot car made them shrink. Had to give them to my step-mom who is 2 sizes smaller than me, and they fit her perfectly. I was going to order a new pair and be sure not leave them anywhere hot, but the price went up since then. Very disappointing since they were very comfortable the two times I got to wear them... There should be a warning in the description about this.
