Pharmacy antifungals - terbinafine or clotrimazole cream, spray, or powder - clear most athlete's foot in a few weeks, but you must keep using them about a week after the skin looks normal, or it comes back.
It rarely resolves untreated. The hygiene half matters as much: wash and dry feet daily (especially between toes), change socks daily, alternate shoes, share no towels, and wear flip-flops in communal showers. Untreated, it can spread into toenails, where it gets much harder to kill. See a doctor if two weeks of pharmacy treatment has not cleared it, if skin cracks, oozes, or swells, or if you have diabetes.

What to do
Common questions
How do you get rid of athlete's foot?
Athlete's foot almost never clears on its own, but pharmacy antifungals beat it reliably: terbinafine or clotrimazole cream, spray, or powder, used daily for one to two weeks - and kept going for about a week after the skin looks normal, because stopping early is the main reason it comes back. The hygiene half matters as much as the medicine: wash and dry feet daily, especially between the toes (damp toe gaps are where the fungus lives), change socks daily or when sweaty, never share towels, alternate shoes so pairs dry out, and wear flip-flops in communal showers and pool decks. It is contagious, and untreated it can spread to toenails, where it becomes much harder to kill. See a doctor if pharmacy treatment has not cleared it in two weeks, if the skin cracks, oozes, or swells (possible bacterial infection on top), or if you have diabetes - foot infections are a different risk class there.
