Need advice for wide shoes

I have been having problems finding shoes that are wide enough to fit. In the past the NB 1004/1005 series in a 2E fit perfectly, but when the 1006 series came out I had to go to a 4E. My first pair was white with navy trim and fit perfectly, but my 2nd pair bought just recently which was black/silver was not close to a 4E, or even a 2E, probably due to the fact the toe box tapers at the end. Does anyone know if the NB 806's have a wider toe box and are not as tapered as the 1006 series? I was given a tip that the KSwiss Hypercourt Express 2E had a lot of room in the toe box, but I have never tried them. Can anyone shed light on this?
