I measure size 9 7.5E.  I usually buy 9.5 6E as the widest size I can get with a little extra toe room.  These I bought as 9.5 5E as the Widet in stock and I had a credit to make the cheap enough to try.  What I like about the shoe is that even though it is not wide enough the side feel sloped instead of a 90 degree wall like other boots in 6E sizes.  The toe seems wider on this boot as well.  Wish I could give 4.5 stars because to only deduction is for no 6 (or 7.5E but that's custom I know) size.

I will buy another shoe made buy Propet for sure and I'm hard to shop for in shoes.
