I've been trying to run barefeet. It's weird!
Seems my feet have to get used to this but my
initial findings are that it's more natural.

The conclusions in the articles above are
interesting and I'm hoping that barefeet running
will help strengthen my feet.

Of course, I don't run totally barefoot to avoid
puncture wounds. For that I wear special "shoes"...
