I've been loving rocking my crutches and broken knee with bare feet. I'm kinda thinking that I want to carry with going barefoot everywhere now I know I can handle pretty much anything without shoes on.
No, but it's very unhygienic to do so. Your feet will get dirty, cuts/scrapes, blisters, callouses just from normal wear and tear. Also, you might break a toenail or if something somewhat heavy falls on your toes, you might end up with a bruised (black) toenail, and those aren't fun. Probably the most important point is that you're at risk at stepping on sharp and dangerous objects (used needles, sharp sticks, etc). I mean, you can live in bare feet but it's not a wise choice to.
I'll also give you props for not giving a shit what people think about you when you're walking barefeet everywhere
If you want to barefoot you should! Shoes are just a way for shoe brands to make money, that's why they tell people they have to wear shoes everywhere - it makes them more money! Going barefoot is completely natural, wearing shoes is not.
Yes, it is. If you live in a place with carpet, it wouldn't be so bad. Otherwise, going outside would be horrible. I have worn out crocs and my feet get roughed up a bit. So, going completely bare would be a lot worse. That's why I have gotten a new pair.
