I had a couple of young ladies visit the house this evening.
One was polite enough to offer to remove her shoes. The other protested that her feet were smelly, but she took her shoes off anyway.
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!
