The sandal that looks like a shoe
To the casual eye, this is a standard loafer. The good quality leather and excellent workmanship are obvious.
However, to the feet that are in these "shoes," they are not standard loafers. They are lightweight, and the soles have significant flex. The insoles are also padded, so these really don't feel like the standard heavy, stiff, clunky loafers. They are very comfortable, yet stylish enough that those around you won't know that you are wearing a sandal and not a real shoe. They don't have much arch support, but they aren't supposed to (it's a lot like walking barefoot).
The sizing is fairly true-to-size. They are not especially narrow, and the leather is soft enough that it eventually stretches out a little.
