I like wearing just socks. Mainly because at the minute it is COLD and my floor downstairs is tiles. Oh so very cold. In summer though I like barefoot mostly, always have done. Especially fresh morning grass with a bit of dew underfoot. Only problem is, as you said, due to this conditioning, our feet are weak and easily cut. And one thing that really is a pain, literally and otherwise, is a cut on the sole. Man. That hurts, but not just that, it is so awkward. It always opens up again.
I also do alot of stuff with my feet. Party because I am lazy, partly because I can. Picking up TV remotes, pens, etc. Lol. Why move when I don't have to?
