The boots fit fine when I first tried them on, and they are definitely water tight. However, after walking in them for about 5 minutes, my left foot started to go numb -- the left boot, just the slightest bit tight, was cutting off my circulation. I had to stop in the middle of the side walk, take my foot out of the boot and move it around before continuing on. I haven't worn the boots since! I know my feet are the same size (I have worn plenty of other shoes), and therefore the problem is with the rain boots. I was very disappointed.
