that sizing looks more like 42.5 EE. This is why you need to try on some other dress shoes (hopefully from AE). You cannot gauge your sizing based on sneakers, especially if you have wide feet. I wear a 10-10.5 in most Nikes, so when I first went to dry on dress shoes I was trying around that size. Well guess what? I worked my way all the way down to a size 8 in Allen Edmonds, albeit in a EEE width.
Ahhh, I see.
Thanks for your input, sounds like I may be in a similar situation.
