For being tall I have abnormally small feet for my height, but they are wide. I ordered 8.5 thinking I would need a little bigger to accommodate my width for getting them on and comfort level. I could easily fit into an 8. Overall nice shoe. Wanted memory foam since I will be doing a lot of walking on an upcoming trip. Wanted a little different look for a slip on. Gave it a 4 since I haven’t wore them for intended purpose yet.
