I wear a 8 length and a AAAA width. My heel is actually more like a AAAAA width. I have a horrible time finding shoes of any kind for any occasion, but I recently bought some clogs from Keen. I carried them to work and put them on there a couple of nights and tried them out. I have decided to keep them. And they do slip up and down on my heel slightly, but I can live with that. I figured that is the way they should do. The left shoe is tighter than the right because of the difference in my feet. Hope this helps. Jan
