What are your favorite / comfiest shoes during pregnancy?

I'm looking for ideas on stylish flats, preferably with wide toe boxes. Don't they say though that flats aren't recommended during pregnancy due to lack of support? I'll probably end up with sneakers (like Pumas- I don't like regular walking sneakers). I have a pair of Merrell clog shoes but I"m getting sick of looking at them.

Also: did you wear flip-flops the last months of pregnancy?
