You can go barefoot in the park, the backyard, on the beach, in the house, even in the steam room. But don’t ever, EVER go barefoot on the airplane!
I know that it’s tempting while you are sitting in your seat to slip off those uncomfortable shoes, and in limited circumstances it’s okay to do so. Here are the rules: No stinky feet (if in doubt, leave your shoes on). No holes in socks (if in doubt, leave your shoes on). Do not allow your bare or stocking clad feet to ever, EVER touch the floor of the airplane under any circumstances whatsoever.
The carpet on the airplane is a terrible, terrible thing. It has gone miles without a thorough cleaning, meaning miles of spilled food, vomit, soiled baby diapers, garbage, disgusting germs and other leave behinds from previous passengers. The airlines say that the carpet gets deep cleaned about once a month. I’ve yet to see evidence of that.
And what’s up with going into the lavatory without your shoes on? Barefoot, stocking foot, I don’t care. It’s disgusting! It’s like you’re saying that you haven’t had enough germs around your seating area, so you want to walk down the aisle collecting more as you go. Then, because you still haven’t had enough, you now step into the lavatory, and walk into the mess left there. Do you wonder why your feet or socks are wet after that? Keep this in mind: That’s not water on the floor in there; it’s someone’s bodily fluids!
Next time you travel, look around. Do you ever see flight attendants with their shoes off? Of course not! We keep our shoes on – and so should you.
