that's interesting. where I live, most health professionals wear crocs. they're quite comfortable, light, and super easy to wash since you can just plop them in a sink.
Psychology students seem to get attached to the birkenstocks and keep carrying them throughout their careers.
Also, Birkenstock soak up blood rather well. Would not recommend in such cases.
With regards to Crocs and washability: Birkenstock seem to have introduced some moodels made from PU as well. Like OP, I'm more familiar with the white leather ones on health workers.
like if you were the one kid wearing "Payless Shoes" instead of the latest of the trendy "Nike" brand
but apparently Birkenstock are back in fashion, in Germany, amongst the younger generation
