If you mean you knap bare footed..... yikes. I have too much of a tendency to drop things. I could just see dropping a big ol piece of obsidian on my foot. I could just hear it now from the other half..... "You big dumb A$%. Why weren't you wearing shoes." Thanks, but I think I will keep my shoes on and just be carefull to clean them out. Actually, what I am going to do is just use an old pair of dock siders that I have and just use them when knapping.
