Certainly a good thought, and something I'm considering. The bigger issue at play is whether I end up wearing scrubs all day or continue wearing my usual chinos + button down shirt +/- white coat. The procedures I do during the day aren't usually terribly messy, although there is a possibility for an errand squirt of blood to end up on my shirt. So, if I were to be wearing scrubs all day, I would usually pair them with a pair of sneakers/running shoes. It may look a little silly and be somewhat pointless to wear nicer dress shoes with the scrubs, and then cover them when necessary.
It really wouldn't be the end of the world to continue wearing what I normally wear, and in that case I may do the booties thing. The other docs in my group and to wear scrubs most days, even the ones who only see patients in clinic. I've never been A huge proponent of wearing scrubs except when in the operating room. I find it more professional to dress in business/business casual clothing, maybe out of respect for the patients.
