Because Athelete's Foot is a fungus, keeping the feet dry and clean is a must. He will need a fungal cream to help get rid of what is there for now. Wearing white socks is a huge help, too, in the healing and soothing process. When feet are wet, they are prime for fungal growth. Scratching spreads and irritates the affected areas. I know that Walmart carries a tolfinate cream that is as good as the name brand to save some money. Hope this helps.
