As I was warned, my feet are definitely tired. The first day, I wore my Ecco ankle boots. They were fine, but not really supportive enough. So I picked up some new shoes today. They were pricey (like, maybe there goes my first paycheck), but I think it will be worth it once I've broken them in.
Anyway. So far so good! Now I get a couple of days off. My real test begins on Saturday -- a full day of work, and the holiday shopping season has begun.
