How to Treat Smelly Feet and Excessive Foot Sweating

Many people suffer from foot odor, which significantly impacts their daily life and work, prompting them to seek effective treatments. So, how can one treat foot odor and excessive foot sweating?

How to Treat Foot Odor and Excessive Foot Sweating

Foot sweating and odor are often caused by poor shoe breathability. It is recommended to wear socks and shoes with good ventilation and to change socks daily. Shoes should be aired out in sunlight regularly. For individuals who sweat excessively, developing the habit of washing feet each evening is advisable. Adding an appropriate amount of white vinegar and table salt to the foot-washing water provides antibacterial benefits and helps alleviate both foot sweating and odor. In cases of severe foot sweating and odor, soaking feet in a potassium permanganate solution may be beneficial. If foot sweating and odor are accompanied by itching and skin peeling, a fungal infection is likely; in such cases, soaking feet in “Jiuguang San” (an antifungal herbal powder) or “Jiuguang Fen” is recommended, followed by topical application of miconazole nitrate cream to affected areas.

Wearing non-breathable shoes and socks raises local foot temperature, predisposing individuals to excessive sweating. Endocrine disorders—such as hyperthyroidism—may also cause excessive sweating in the lower extremities. Additionally, overactivity of the eccrine sweat glands in the feet can lead to increased perspiration. When foot sweating is excessive and hygiene is inadequate, foot odor commonly develops. This occurs because moisture creates an ideal environment for bacteria and fungi to proliferate, breaking down accumulated keratin and sebum on inadequately cleaned skin and thereby producing unpleasant odors.

Individuals with foot odor should wash their feet frequently and change shoes and socks regularly. Choosing well-ventilated footwear helps reduce the occurrence of foot odor. We hope this information proves helpful!
