I bought these in gray and love them.  I found them to be true-to-size: I usually wear an 8.5 and that's what I ordered, and they fit fine.  My foot width is about average.  One thing to note: Pumas (specifically Speed Cats and Repli Cats) do tend to fit tighter and narrower than other sneakers, it's been true of very pair I've owned and it's just their style, so these aren't shoes you'd want to wear if you'll be on your feet for 10 hours straight.  These shoes are great and they look cool, but I've definitely had to loosen the laces after wearing them all day!
