When traveling and trying to stick to suitcase weight restrictions and still cram in everything you need for your trip, you sometimes end up packing your shoes right next to your clothes. Yuck. Shoes, even clean-looking ones, harbor tons of outside germs that you likely wouldn't want touching your bare skin. Head to the dollar store or a beauty supply store and purchase a package of disposable shower caps. They're plastic and have an elastic opening. Stick your shoes, soles down, into the shower cap, then pack them away in your suitcase.
