I bought these slippers, based on reviews.  I have a very narrow foot(A-B width), and it's hard to buy footwear, period.  Anyway, the big complaint with these slippers, is that they are very tight in the opening.  I suspected, correctly, that this would make them fit better for me.  I don't LOVE them, as the bottoms are very loud on my wood floors, but they are relatively comfortable, and the tightness in the opening is fine with me.  Once they loosen up a bit, that might be problematic, but I'll cross that bridge when I get to it.
