I will be going on an extended trip and will be packing 3 pair myself this time. I just do as other say and put socks in them and then put them in plastic bags, they go on the bottom of my suitcase around the edges.

Normally I travel with whatever I am wearing and then a second pair in the suitcase, but this trip I have several "nice" evenings with different dresses and obviously different shoes for the dresses.

Hey, sometimes, a woman just has to have more shoes.
