I know it's gross but I've seen this from time to time in my son since he was only about five. Sometimes the skin turns grayish white on the sole, gets very moist and peels off in thick patches. We've tried all kinds of foot powders over the years but nothing much seems to work for long. Of course by the time you get the appointment for the dr, it's stopped so it's never been treated by a doc. Any ideas on what to do?
I'm guessing it's from sweat but it could be something entirely different.
