I found them uncomfortable and after that I decided to continue running barefoot because I found it more comfortable. I felt more in touch with what was happening - I could actually feel the track.
I run in a pair of New Balances with a thinner sole, but they're nothing like those barefoot shoes that show all five toes. I have a bit of a phobia about those.
Once, right before a show, I realized I'd forgotten shoes. I didn't want to wear my flip-flops onstage because I could trip. I ended up going barefoot, which actually worked out because it became my 'thing.'
