If you're going to wear a captoe, Carlos Santos is sleeker than AE: http://us.skoaktiebolaget.se/collections/carlos-santos/products/carlos-santos-black-dress-shoes

I like Carmina, but that 50% upcharge for MTO is ridiculous. Seriously you can get their shell boots for $932.73 shipped, taxes included. It's a shame. You might be able to get a GMTO going, they are a really sharp looking pair of boots.
I think Forest is roomier than Rain but you should research that. Rain in normal width is better for D or E footed people with wider heels and moderately high insteps. If your foot is pretty narrow you'd probably do better with Simpson and I'd guess you at a 10.5UK. Maybe 10UK in Rain but I think you'd find the shoe feeling big volume-wise. I'd email Skoak for sizing advice in addition to what feedback you get from this thread.
