I got three thorns in the ball of my foot while out on a run, about 2 miles from home. I couldn't deal with it on the spot so I walked home, got my camera out and filmed getting them out. The whole thing took about 20 minutes and here is an abbreviated video of it. This doesn't happen a lot, so I made a note to myself that if I ever get a thorn I wanted to film getting it out. Maybe I'll do that for a glass shard if I ever get one again. Note that the skin is pretty thick and there was no blood involved. It did hurt a little bit but not much.
When I get more time I will make and post more barefoot running videos.
