What should I wear tomorrow??

I am going to a party tomorrow. I just got new shoes, and I really want to wear them. Okay, we are going to be running all over the place at a carnival tomorrow, and then we are going to a cooking cl. I just got some puma's, and some keds. Should I just wear old shoes? I don't want to get them dirty. I just got them two hours ago. What would you recommend?/do?
