It really does make sense to leave the smelly, dirty shoes out in the hallway and step into the house with clean socks/feet. Or, if you'd like be really Chinese, you can wear slippers inside. We have such a collection of slippers...ones we purchased, several from the hotels we've stayed at, and gifts from people that I have a bucket by the front door full of slippers for ourselves and guests. Any guesses to the color of Jamie's? Bright Illini orange, of course! The slippers are also helpful in the winter when it a tad bit chilly in the apartment.
Now, make sure your toe nails are painted pretty and your socks don't have holes in them and come on over for a visit.
