Fill your bathtub with hot water. As hot as you can stand without hurting yourself. Let your feet soak in that water for 15 minutes. After the soak scrub the living hell out of your feet with a pumice stone. What looks like dead skin will scrape off your feet. It's not skin though, those are microbes, the bacteria that causes foot fungus and bad odors. After the scrub clean your feet with soap and make sure to scrub between your toes. As for the fungus you can treat it with peroxide but don't use it too often. Maybe twice a day. It can actually aid in fungal growth if over used. Change your socks every day. Powder your feet and shoes with Gold Bond foot powder. Use the pumice stone once or twice a week and you should be fine in a week or two. You Might want to consider a new pair of shoes too.
