Bacterial growth within the shoes that can produce odors. To avoid odor simple follow any one of the below easy steps:
Vodka :Vodka is odorless and hence won’t leave any traces behind. Spray some on your shoes to curb bacterial growth.
Alternate shoes: Avoid wearing the same pair of shoes two days in a row. This gives them a chance to air out before you wear again.
Freeze out the smell: Put your shoes in freezer-size sealable plastic bags (one per shoe, if necessary) and put them in the freezer overnight. The cold should kill any fungus or bacteria causing the odour.
Newspaper :Stuff crumpled newspaper inside the shoes to help absorb both moisture and odors. Don’t wear them until they are completely dry.
Salt: Salt has been reported as being effective in canceling out moisture which causes the bacteria in shoes to smell bad. Apply 2 teaspoons of salt into each shoe and they will smell better in a couple of hours.
Tea bag: Are you a tea drinker? Well, stick a couple of tea bags into your smelly shoes. In fact, stick them in all your shoes to keep them fresh, especially if you keep them in the closet with all your clean clothes. You don’t want icky funk sticking to your clean stuff — especially if you have to lug your laundry to a laundromat.
orange peels : Place orange peels in the shoes and let them sit overnight. Discard the peels in the morning. This will get rid of odors and create new, fresh smells.
Baking soda: sprinkle baking soda inside the shoes and leave them to sit overnight. The baking soda will absorb the odors. In the morning, empty the baking soda into the trash. If this is a recurring problem, you may need to repeat this process every time you wear them.
Talcum powder: If your feet start smelling when they get damp, then a good way to keep them from getting damp (aside from giving them a breather every once in a while) is to powder them with baby or talcum powder. The powder has a pleasant, but subtle, smell to it and could help your feet from sweating in the first place.
Deodorant : Put deodorant on your feet. This might sound weird, but keep in mind that your feet sweat too. Buy a stick of deodorant that is meant only for your feet (that is, don’t use it anywhere else) and apply it every morning.
Heater:Dry your shoes by putting them near a heater or in a warm sunny spot.
