After wearing any full leather shoes or boots (I wear dress shoes for work a lot) my feet get these clear blisters on them, and not due to friction - I really can't explain it. I thought maybe athelete's foot, but the typical treatments do not work, even after several days of applying them. After about a week my toes get cracks under them, and the skin peels. About the only thing I have been able to do is soak them every night, and that will not be practical on the trail. Anyone have a clue as to what causes this, and what to do about it? My guess is that the leather doesn't breathe, and the sweat of my feet sort of scalds them. Short of spending a lot of time without my boots on (again not practical on the trail) I'm not sure what to do.
