Ummm not if running on a trendmill but playing squash which I do mostly I play bare foot.
And walks which is probably my second mot common form of exercise, I also do barefoot.
The cut in the center of my foot btw is from stepping on glass.
So just the cracks I'm worried about.
what the hell? You just answered your own question, get some decent running shoes. http://www.asicsamerica.com/
