Today's shoes are the Camp Moc and Blucher Moc. They are quite a few brands making these and it's not hard to find them made in the U.S.A. These are kinda like a go between of a moccasin and a boat shoe. Personally I'd go for the blucher moc, there a bit more manly. I had a pair of camp mocs a few years ago and I found them to be a bit dainty, it must be something about the bow with no eyelets.
