I have looked through the archives, and there are a few threads on similar topics (e.g., here, here) but I don't see anything that is directly on point, so I'm going to tee this up.
We are going to Sicily (around Catania), Naples, and the Sorrentine peninsula in October. We are going to do some hiking, as well as some sightseeing. I know we'll go to church, and who knows where we might wind up for dinner. My plan had been to wear slacks and an unstructured sport coat when not on the trail or the beach. At home, I generally pair that kind of outfit with loafers, but I am trying to see if I can get away with a single pair of shoes that will tackle trails and then, with a dusting, get by in town and in church. Would something like an Alden Indy boot, or a pair of Russells, do the trick in those parts?
(And yes, I know that even my Italian genes won't keep me from being noticed as an American---we'll have too many children with us to be Italians, for one thing---but I try to make it a point not to be an ugly American, in any sense of the term.)
