Do you ever look at the floor when you're walking through an airport? Probably not. Your eyes are up, searching for your gate, the book store, or your last chance at an adult sized bathroom stall.

And yes, those are my excellent Perfect Airport Shoe traveling clogs you can see in the photos. They work better with each trip!
