The best thing to get rid of smelly feet is relatively simple. Before putting on your socks dust some body or medicated powder over your toes. Fold a piece of tissue /toilet paper lengthwise to about an inch in width and insert the tissue into all your toes ( this is to absorb the moisture ). This is even effective when you are wearing waterproof shoes, where the moisture from your feet is trapped inside the shoes eg hiking shoes. Try it and you find it really works.
