After cleansing and drying your feet thoroughly, apply a thin layer of antifungal ointment/cream twice daily (morning and night) until the rash clears, then continue for at least 1 week more to prevent recurrence.
Health Tips
Good foot hygiene is equally important: keep feet dry, change socks daily, avoid re-wearing the same shoes every day, wear breathable footwear, and don’t share towels or shoes. 
If no improvement in 2-4 weeks, or if the infection is widespread/thick-skinned, oral therapy may be needed.
