Apologies, I wasn't trying to start a shoe jihad. My only point was similar to above people should be careful with blanket statements about shoe fits. Rain is generally viewed as a wide fitting last and Simpson a narrow fitting one. I believe those are good rules of thumb--but exceptions apply.
Medium-to-narrow-width foot? Most here would disagree. I love the Rain last were EG "F" and Alden "E." Very glad you like the shoes, but above is not good information for folks. I do concur they are quite cool looking shoes.
The heck with the boot, that gunboat is very cool. I am sure the Rain last will be fine, but the Detroit last appears (pardon the pun) tailor-made for the Scotch-grain leather which I like to see with more rounded lasts. I am not going in on this though.
