Who thinks they have tough soles. I have been barefoot for 5 years running and have the toughest soles that I know of. Knives bounde right off. I can step on a thumbtack and never feel it. Strangely, my feet do not look tough. They are soft, smooth, and have some little callouses that act like steal. The other day I was running a forest trail. I decided that I was going to be adventureous and run off the trail in the brush. About 2 minutes into the run, I stepped on a thorn plant, yanked it out of the ground, and never knew it. The thorns didn't hurt. I pulled them out and it bled a little bit, but nothing happened. In school, the same thing happedned, I stepped on a thumbtack and never felt a thing. Because of this I go barefoot even when the is visible glass, and on construction sites. Glass just breaks under my foot and never does anything any way. I love going barefoot, it is the greatest. I have a girl friends whos soles are even tougher than mine and are always black from going barefoot. Even though my feet are that tough, they are still as sensitive to the grass, the sand, the moss, and all of thoes wounderful reasons to go barefoot, as I was the day I started. My girlfriend has very beautieful feet to. Perfectly shaped toes, lovely tan soles and tops. I give her foot massages regulary but right now she has a cut on her foot from some glass that she stepped on from the beach.
