Can anyone tell me what cheap home made remedies can I use for extrmely rough dry heels on feet?

Vaseline. Get yourself a foot scrubber for about $1 at any drug store. Then soak your feet in warm water, avoid soaps because they dry skin. Immediately after drying your feet, put moisurizing lotion like eucerin or aveeno, (oatmeal) and seal it with vaseline. Cover overnight with cotton socks. Continue daily for 7-10 days, and you should see a big difference.
