Thanks for the replies. I would have agreed women wearing proper heels ie above 4 inches is unlikely to return but then I thought back to the period of 95 to 2005 for example. I dont recall seeing many women in the offices and bars wearing them then either, that came bk a few years later....so who knows.
It struck me that in offices and malls etc pre heel height craziness around 2004 to 2016 ish....and then 'me too' they're weren't many sightings. Perhaps things will come full circle?
