The Barefoot Airplane Problem

I took a plane to Reno today. The problem with taking your shoes off on a plane is not so much the actual taking off of the shoes. The problem lies in taking off the shoes, and then proceeding to take over your neighbor's space with your barefeet. Taking off your shoes and resting them comfortably in your space, right in front of your seat or under the seat in front of you is good. Taking off your shoes and crossing one of your barefeet over your knee, with your ankle up on your thigh, and your barefoot hanging out into your neighbor's space, often touching their thigh, is disgusting. Keep your barefeet off me.
