I actually stepped into a newly broken glass bottle today. I was walking up the stairway in my university, and someone had dropped a glass bottle from the very top. I felt something crunchy and I thought I had stepped into cookie crumbs, but when I looked down my foot was deep in glass shards. I dusted it off. Felt nothing, after only 2 days of walking barefoot. I later took a closer look and found a pretty deep cut, just not deep enough to be felt. Guess you get used to this pretty fast.
The one thing annoying me is that I still have some sore spots on the balls of my feet. I land on that particular spot when walking and running, so there's really no avoiding it. It feels like a blister, but I can't see one. Maybe it's just getting too hot and will resolve itself in a few days.
Today I got offered shoes by a friend. It was nice
He was worried. I declined. Someone else asked if I'd been robbed.
Weird: I have sore muscles in both my calves and my thighs, just from regular walking (not even much, maybe 1-2km today). Seems you use a few muscles that atrophy when using shoes.
Atm it's still fun, hope I get more resistant soon so I can run around instead of "carefully tread".
