I have dry skin... are there any good products for taking care of my elbows and heels?

The seasons have changed drastically in an instant. How can this happen so suddenly...?

So, my skin and body are the first to sense the change in weather. Since I have dry skin, I am particularly sensitive to the seasons right now. My nose, lips, arms, legs, and even my feet feel tight and dry. Because the dryness is severe, my elbows and heels are even worse. My knees, too... These areas require extra generous moisturizing care to prevent cracking, flaking, and white patches from becoming more noticeable. What products should I use? I realized that just applying body lotion wouldn't be enough. It is especially difficult because my heels crack so much. Please recommend any good skincare products or methods you know of.
