When I know I am going to be on my feet for any length of time, I will cut a Lidoderm patch in half and put on the top of each foot. Really works this way.

In an earlier post somewhere, someone mentioned about using Eucerin Calming Creme so I bought a tube. I rub it on my feet just before bed every night and it sure does "calm" down the feeling I have in my feet at the end of a busy day.
