Are you looking for a specific type of shoes, or companies in general?
Thursday Boot Company has wide options for a lot of its inventory (only up to EEE though from what I can see); many of their products are resoleable, but Everyday Gear did a 3-year test on the non-resolable low-top sneakers and had good things to say. And my Jim Green Razorback boots are extremely wide despite not being labeled as such. Solovair’s Last 5400 boots are said to be wider, but there aren’t any specific size conventions lifted. And you can customize pretty much everything with Nick’s boots, but get ready to spend $800.
Hope others can provide better suggestions. I struggle with this myself in the women’s section now that I’m no longer shopping fast fashion. Red Wing has D sizing (which is the women’s wide and men’s average E width) that stops one size below mine, and that’s just one example, so I’m stuck with W width for most shoes and brands. So I just live with the pain until they’ve been broken in 🙃

















Actually, after reading this and doing some research, I think Keychron would be a good choice. Thank you for taking the time to write this!
