In the Hastings shopping mall today, I saw a girl put her feet up on a bench. She had removed her boots before doing so.
I also saw a young man in a clothes shop who had removed his shoes before setting up a window display.
This blog recommends that you adopt a shoes-off policy in your home, not just for family but also for guests and other visitors. Socks, slippers and bare feet are fine indoors, but not shoes. Just say NO to shoes in your house!
