My (Asian) parents keep on telling me to take my socks off whenever it's summer because they think that the feet need "fresh air" and that they need to breathe and that keeping them in socks all the time prevents them from breathing. They also think that wearing socks can contribute to foot fungus when it's warm. And they say that the "damage" will just "accumulate" over time, whatever "damage" that wearing socks most of the time actually causes...
They also tell me to at least take my socks off when I sleep.
I'm somewhat more sensitive to cold than most people, so at any given temperature I generally dress in more layers than most people. I also live in Seattle so it almost never gets to temperatures warm enough for me to take my socks off. Frankly, it's a matter of personal preference, and they shouldn't interfere with it.
I'd like to finally convince them that what they say is pseudoscience, but frankly nothing I look for will convince them, unless someone can finally authoritatively address the question for once and for here.
