How about you just keep your shoes on...??
That depends on many factors. Don't just judge everyone - once you'll be in the same position someday, you'll be sorry.
First of all, age matters a lot. Up to around 25 years old, I never had these issues. I could wear the thickest warmest socks/sneakers/boots and I would feel just fine. Sure my feet were hot, but it would bother me none, and my feet didn't smell much. I laughed at older people that would take off their shoes or complain about hot, sweaty feet.
Now, much older, I know better. I work as a support tech, and I sit all day in a steamy, cramped office. Often, I have to go all over the building to crawl under the tables and fix computers - so good shoes are not an option. I need something that I don't feel bad about destroying. I wear cheap black sneakers, and my feet stink, and I take off my shoes in the office to relieve my suffering.
I use GoldBond powder every morning, and that takes away the smell, so my co-workers don't have to suffer with me. ; )
