I have a pair of MT 33s. They are stiff and supportive, and the soles are very durable. I have used them for touring and regular commuting/transportation for a couple of years and they show little wear. Because they are not supple, they are not as comfortable to walk in as, say, sneakers, but they are not uncomfortable. You will have to decide if you will be comfortable walking around in your road shoes while touring. I tend to do a lot more walking when I tour vs. road riding. Walking takes it toll on shoes. You might find that, in the end, it's more cost effective to have a shoe that was designed to be walked in more extensively than a road shoe is.
