I just bought some pretty nice shoes. I didn't buy them for the AT ... I just wanted them. I think they would be too cold most of the time, but a great summer shoe! "Five Fingers" by Vibram. They really do feel like you're barefoot, however, they are pretty pricey. So far I love them! Check them out guys and see what you think!
