What is causing my feet to smell bad?

The feet and hands contain more sweat glands than any other part of the body, with roughly 3,000 glands per square inch. Smelly feet are not only embarrassing, but can be physically uncomfortable as well. Feet smell for two reasons: 1) shoe wear and 2) sweating of the feet. The interaction between the perspiration and the bacteria that thrive in shoes and socks generates the odor. Therefore, any attempt to reduce foot odor has to address both sweating and footwear. Persistent foot odor can indicate a low-grade infection or a severe case of hereditary sweating. In these cases, a prescription ointment may be required to treat the problem.
