So back in the mid 2000s, I was an international student at a US university. I had the assumption that everyone in America wore shoes or slippers indoors, an assumption that was created from hearsay, so I bought a pair of flip flops that cost a dollar, and wore them each semester.
The thing is, is that I never got to be barefoot. I was always and everywhere barefoot when I grew up so going for months without the opportunity of being barefoot was in hindsight a small but real stressor (I would at least take showers barefoot in the shower stalls, where on average five or six people would share two stalls; they were relieving).
The funny thing is that I went to US and UK schools when I was young, but not in the US or the UK -- I lived in countries that had schools for American or UK nationals that also accepted international students, and thus never expected a culture transition to happen. I had not realized that back then I never encountered a house that wore shoes indoors; my parents wiped the floor clean before going in so that the dirt never touched our feet, and my friend's house that I visited never wore shoes either.
In other words, when I first stepped foot in the US mainland, it came as a culture shock that wearing something indoors could be so darn uncomfortable.
My question is : in the case of dorm rooms, is it inevitable that unless you want your feet to pick up diseases, your feet will have to be wearing something? Or can you still attempt a major clean up of floors or carpets in your dorm room such that you could free your feet? What if you have roommates who don't share the same custom?
My other question is : I found that school custodians deep clean carpets in dorm rooms during the summer, but does that mean I can go barefoot on carpets? Could someone enter the room after that deep clean wearing shoes such that the deep clean is rendered meaningless if you were to aspire going barefoot?
Last but not least : Should you give up trying to go barefoot if you are in college dorm rooms, and only try something like that out in your own house?
