Apple Cider Vinegar Antibacterial and Antifungal: MD Podiatrist

Bye-bye, stinky boots. “Apple cider vinegar (ACV) is antibacterial, and can balance the skin’s pH levels by killing the bacteria that causes foot odor,” says Daniel Michaels, DPM. Foot odor is caused when the moisture (sweat) on your feet interacts with bacteria, and since bacteria thrive in warm, moist environments, the inside of your socks can be a petri dish of sorts. By using ACV to clear away some of that bacteria, you can subtly lessen foot odor.
You may have heard of using ACV to get rid of dandruff on your scalp (which is caused by an overgrowth of yeast and fungus), and the same principle can apply to using it on your feet. According to Dr. Michaels, it has anti-fungal properties that can help to treat skin and nail infections.
