Regarding Crocs...the facility I was working at actually had a policy that said they aren't considered appropriate foot wear, and so if you had an accident with them, good luck getting WCB (workers comp) involved. They look comfy but I have yet to get me a pair...at my new position I get to wear "professional clothes" But on lab days I wear my scrubs, even though they are all simulation excercises and we wont be dealing with actual fluids it's always good to have something you can wear and not have to worry about stains and the like.
