Some people may be able to just use a foot deodorizer, but it really depends on the case. If you want to fight the odor effectively, there are few things that you need to do. Wash your feet in special soak, try to put your legs for ten or fifteen minutes in the bowl with the soup. Antibacterial soap will be the best one in this case as it will clean and also sanitize your feet and help remove any bacteria or germs that may be trying to grow in the damp warmth of your feet and toenails. Using a towel is very important. You must dry your foot so the bacteria causing the odor will have more difficulties in spreading. You should wash your shoes regularly and make sure that they are breathable enough and use a germ-killing spray on the insides of your shoes at least once a week to keep germs and bacterial and fungal colonies from being able to get established.
