I am going to a new group meeting in a home for the first time, so I must make sure I wear shoes which I can more easily take on and off in case it is expected. Whilst I understand the thinking, to me it feels weird in a social or semi-formal environment, sitting, or worse, standing, in socks or bare feet.
My feet easily get cold so I take slippers if I am going to family. They always remove their shoes at my house, though I tell them they needn’t, unless they are muddy.
DH would never take his shoes off. His foot specialist told him to always wear shoes, and latterly, he could not have managed to get them on and off without a struggle.
I appreciate that people do not want their carpets dirtied, but some consideration needs to be given to the difficulties some of us have with shoes and feet. A chair is a help. So is a shoe horn.
