I have a classmate who's from India. I've never seen her wearing closed-toe shoes or socks. She wears flip-flops and sandals to class throughout winter, even when it was snowing here in London.
One day I asked her if her feet weren't cold and why she didn't wrap her feet up warmly. She replied that she just wasn't used to socks and closed-toe shoes. She was always barefoot back at home, and after she bought her first pair of closed-toe shoes in England, she felt really uncomfortable and confined in them and never wore them again despite the freezing cold.
I was actually quite shocked that she never wore socks or closed-toe shoes in the 18 years of her life before she came to England. I guess it's only normal given the climate in India. And after some thought, I figured that I'd also wear flip-flops all year round and never wear socks if I lived somewhere like Singapore. After all, that's what I did during my summer holidays in Taiwan.
So... that's why I wanted to ask you this question! It might also help to say where you're from! Thanks ^^
