Zero, I have the same issues.
I found a long time ago the "best" shoe overall for me is Alden's Aberdeen last. I need more room than a typical D width, and its just about perfect. But then again, I am a loafer/slip-on guy, and their tassel loafer and full strap loafer were basically my staples. They have enough colors to make it all work. About 10yrs ago I tried the Alden Shell LHS. That is a little fuller than even the Aberdeen, AND, I am able to wear a D width in that. I have the Alden model which is fully leather lined, and as a casual shoe, I wear it with thin socks, or no socks. BB sells the shoe unlined. So you can even grab a little more "volume" with the unlined model if you need it. I say that from theory, not experience. I don't currently own any of the BB unlined model. But try them. They come in calf, too.
English shoes for the US market tend to be too tight/narrow for me, and I don't live in a major city anymore, so its difficult to keep trying on different models to narrow it down/find a size that works. When I find myself in NY, I am busy, and don't have a day to make the circuit to simply find a pair of shoes that work. So the English shoes aren't on my radar right now.
I've tried recently to branch out into AE. I had a pair of Park Aves and they are on such a narrow last, it killed me. Retailer failed to point that out to me, and even an E width was uncomfortable. Thought the laces would allow adjustment/flexibility. No go. Park Aves are gone. I've since been educating myself on lasts, etc, so I don't have to pay that "tuition" again.
Onto the AE Westchester---another loafer. D width is tight in the toe box and across the ball of my foot. E width feels great up front, but I get heel slippage in the back. Very frustrating. I like the shoes a lot, however, and I am thinking of sticking with the Es, and talking to a good cobbler about placing another layer of lining just in the heel area. I think that could be an excellent solution. I'll see. Going down a half size while staying in the E width was better than my correct size in the D width, but still uncomfortable.
Lastly, if you can deal with something like a MacNeil wingtip, take a look. Not necessarily for suits, but great casual shoe. The laces do offer the ability to adjust. D width are brutal up front, E width is ok. Same last as the Westchester, but the heel issue isn't an issue at all because of the ability to lace. Alden wingtips are on the Brrie last, which I understand to be a nice full last, but I've never tried them, as they only come in Shell, and they are quite costly. I have several Shell pairs in the Alden loafers, and to me, calf is nicer---softer, takes a higher shine, etc. These are next on my list however. The issue with Shell is that some think you need to size down. I have not found that to be the case. THat being said, if others think that, it simply tells me that there is "wiggle room," and THAT sounds like what you need. The little bits of volume here and there with a shoe. You are going to have to try a lot of shoes on. Trial and error.
I am having to get little creative here, and think outside the box a bit, but it is not the end of the world. Check out the Aldens. They really do work best for me, and I still have my first pair from 1986. They don't look new, but they look fine, and I would not hesitate to wear them in any situation. Care for them properly, and they will last. Buy quality, and when you find a model that works for you, stick with it.
I will be watching this thread with interest to hear what others are doing. Hope this helps.
