Geraldine, I wear Birkinstocks and their cuter sister brand called Betula all of the time, they are my favorite summer shoes and the only shoe that I wear as a "house shoe" or slipper at all. It the winter I just add a soft all cotton Gold Toe sock underneath to keep my feet warm. When I was working, RN. I would wear their line of professional clogs, these you could wear with jeans or long pants, and are comfortable enough for a PN'er.

hope this helps!
