You could probably be having plantar keratoderma
Now to treat your skin, use an emollient
multiple times in a day. Soak your feet in warm water twice and apply steroid salicylic acid
ointment daily. once the ointment is applied cover your feet with cling film for an hour. This would ensure better penetration of medicine and faster resolution.
Once the skin improves, continue emollient and stop ointment.
Hope this helped.
