What can I do about sore heels from work?

I work in a food place in an amusement park so I stand around most of the day, or I'm making food. I try not to stand on my heels for a long time but I don't really think about it. When I come home my heels KILL me. I'm going to the mall tomorrow to find new shoes but is there anything else I can do for my sore heels? Like something after work or any way I can get used to it?
