I've got wide feet.  I've been buying 4E width shoes but always feel like I was wearing the boxes, so I decided to take a chance and order the 2E.  I think 3E would have been perfect, but these are very comfortable and look good enough to wear to work (but then I work in a software company - pajamas look good enough to wear around here!).  I've always liked New Balance shoes, and have pretty much gone to buying nothing but them and Propet shoes.  The price on Amazon for these was good, even compared to the vendor's own web site.  No complaints at all.
