You should make an appointment for him at a podiatrist. It may be some sort of fungus. And if you sleep in the same bed you can get it maybe.
Sounds gross! Get him to a doctor!
Have him soak his feet in some hydrogen peroxide and water for about 10 minutes once a week. And change his socks.
You can buy hydrogen peroxide solution at your local drug store or pharmacy without a prescription.
He may have athletes foot. Buy some Tinactin and use it for a few weeks. It's also at your local drugstore.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
