I have a pair of steel toed workboots I bought from a fleet supply type store. I wore them a few years ago since they worked with my costume that year. They worked well enough that I've worn them ever since. They're water resistant enough to shed rain, they're fairly warm, they have good ankle support for standing long periods of time, and the steel toes are an added benefit if a patron gets scared onto my feet.
Granted, I don't run at all, and don't have to walk around much. If I was more mobile, the steel toe may be too heavy to wear all night.
