Athlete's foot, also known as tinea pedis, is a condition caused by skin fungal infections affecting the superficial layers of the skin on the feet. For treatment, one can opt for antifungal ointments, and when necessary, oral antifungal medications, which are very effective in killing fungi.

However, using home remedies like soaking feet in white vinegar, salt water, or applying garlic locally is not advisable. These do not effectively kill the bacteria and can instead damage the skin barrier and irritate the skin, potentially causing symptoms such as redness, flaking, and itchy sensitivity.

If the concentration of vinegar is too low, it is ineffective; if too high, it can be intolerable for the skin. Therefore, if you have athlete's foot, it is best to opt for proper antifungal medications and ensure treatment for a sufficient duration.
