The Mother Nature Network suggests rotating pairs of shoes, scrubbing feet in the shower and wearing well-ventilated shoes and clean cotton socks to fix smelly feet. Some people also use antiperspirant on their feet to prevent sweating and use foot soaks to eliminate odors.
According to Chanie Kerschner of the Mother Nature Network, feet smell because of sweat. Because feet are normally covered by socks and shoes, the sweat cannot evaporate. Bacteria then begin to feed on the sweat and excrete an odor.
Everyday Roots says the key to eliminating foot odor is keeping feet dry and clean and fighting the bacteria by soaking the feet. A simple soak to make is an Epsom salt foot soak. Dissolve 1/2 cup of Epsom salt in 8 cups of warm water, then soak feet for 30 minutes at least once daily. Thoroughly dry the feet afterwards. Epsom salt neutralizes odors. Another method is to pour 4 cups of hot water in a foot basin and add 5 bags of black tea. Allow the tea to steep for 10 minutes, then soak the feet for 20 minutes once a day. Another tip is to sprinkle shoes with baking soda. Baking soda absorbs odors, helps keep feet dry and kills bacteria.
