I don't know why I didn't think of this before. I use this not only when I'm travelling, but also when camping. (I guess I'm travelling then too, huh?, never mind then.) Great for Portland, Oregon's rainy weather. Just bring extra pair of shoes to wear and put your muddy shoes in these bags so the rest of your clothes won't get muddy as well. The  nylon fabric is a must because that is what makes it waterproof. Also, you can set up a whole outfit on a hanger, then put the shoes you want to wear with that particular outfit, then hang this as well on the hanger, and voila! you're set for tomorrow! I'm telling you, great for OCDs like me!
