I ordered these in my normal size (8) and could not get my foot into without a TON of tugging, pushing, and the use of a shoe horn.  Now, I must admit that my foot is somewhere between a medium/regular and a wide width.  But usually, I only need wide in fancy pumps...and I've never needed a wide on any Aerosoles shoe.  I have, over the years, ordered MANY (and worn out and ordered more) of this style of shoe from Aerosoles (the ones whose names begin with "Cin").  And, I have never had a problem.  So, I don't know what the issue is with this shoe.  If you have a widish foot, or are a larger size, you might consider ordering up a size.
