OMG, totally love all the Dansko shoe styles available. I rotated with an ortho PA who wore the exact shoe you have shown. I think the biggest issue is with the toes in case needles drop and body fluids drop on you.
Well the backs of my heels have been hurting a lot lately (both in my danskos and born shoes) and the thought of letting them breathe a bit is really appealing. Plus the shoes above actually look kinda cute to me (and I could see myself possibly wearing them outside of the hospital) and danskos don't at all...
