I've had them for just over a month now and I've been wearing them every time I go out.
First they are actually very warm. I wanted them mostly because my feet get cold in the office. Since I've had them that isn't a problem. Walking outside I don't feel the cold on my toes at all. They're very comfy and feel like little pillows on my feet.
Secondly there was pretty much no breaking them in. I felt no pain the first few times I wore them which is usual for new docs. No annoying blisters anywhere, no rubbing. Nothing. These have been the easiest shoes to break in I've ever had, including other brands. They've been so easy since they're faux fur lined, that's added padding and taken away all discomfort. The fit of them is narrow due to the lining. However they do stretch after wear like all docs. I got my usual shoe size and they fit fine.
