My fathers feet is swollen look like elephant feet and peeling real bad what could it be?

Get him seen by doc.: One sign of congestive heart failure is feet/leg swelling, thus he should be evaluated by doc. Prolonged swelling causes distension on the skin areas, reducing blood supply and the cells slowly die, thus skin sloughing off. Heart disease is often resulted from atherosclerosis which is caused by high bp, cholesterol, smoking, diabetes etc..Some meds can make swelling worse. Consult doc. Good luck.

Lots of things: It could be many things including heart failure. He should get to a doctor as soon as possible.

Peeling : Often comes with swelling ...He may have venous insufficiency, lymph edema, there is a condition called elephantiasis though this is less likely. The concern would be to make sure no issue with his heart, so if the symptoms are new make sure his internist or cardiologist is aware.
