I think people who are after the newest it boot have moved on long ago.
I'm not sure why mum boots is such a bad thing. Most of us wear clothes to fit in - very few of us are truly individual, visionary dressers.
Wear whatever suits your frame, lifestyle and personal preferences. If that happens to be what the high street offers at the moment, you should be happy: you have lots to choose from. If it's vintagey / experimental / avant garde, you probably won't need anyone's advice. Most of us have committed some style crimes - surely wearing mum boots, Pistols is no worse that the frizzy perms and shoulder pads we all once had?
