Soft Hands, Soft Feet

For Soft Feet
Apply lotion / Vaseline nightly to feet.  Then put on socks.  This will moisturize your feet as you sleep.

For Soft Hands
Apply lotion nightly to hands.  Then put on gloves (any cheap cotton pair will do just as long as your hands are covered).  This will moisturize your hands as you sleep.

Tip:  You can also apply lotion during the day and wear socks and gloves over your feet and hands.  For hands, take out one of those bottles of lotion you have but aren't particularly fond of and apply it after each hand wash.  Even though it seems like a waste, it isn't because 1) you're getting some use out of a lotion you wouldn't be using anyway, and because 2) applying the lotion moisturizes and protects your hands during hand washes, which actually makes a world of difference.

After one week of daily application, you will notice a great difference in the softness and smoothness of your hands and feet.
