Foot odor results from excessive perspiration from the more than 250,000 sweat glands in the foot, combined with the presence of a warm and dark environment. It is a perfect breeding area for a variety of bacteria and fungi, the main causes of foot odor. During a hot day, a foot can perspire approximately four ounces.
Daily hygiene is essential. A foot scrub brush, or a surgical scrub brush can be used to effectively clean the bottom of the feet. Synthetic socks that contain polyester, acrylic or nylon create an environment that promotes odor. Merino wool socks are the best for eliminating foot odor and being the most comfortable. The use of a household product called "Soft Scrub with Bleach" is very helpful. Change your shoes daily to let each pair air out, and change your socks, perhaps twice a day if needed. Foot powders, underarm antiperspirants, and soaking in bleach and water can help lessen odor.
