IMO, I could care less if someone is wearing brown boots or black boots or a leather jacket or a desert flight suit. They are all approved uniform items and who the hell cares? The only thing that I don't recommend wearing until you get your wings.....is your wings (or having one of those license plates). Anyone who spends their time and energy worrying about stupid crap like what color a SNA's shoes are is probably from a community that will remain nameless but starts with P and ends with 3 .
