winter is here, and my heels are cracking. what do you guys do for the skin splitting at the back of your heels?

It's been a while since this has happened, but I've been running pretty regularly lately and the calluses are building back up on my feet, and then the skin split on the back of one of my heels.

I just throw a Band-Aid on it usually, but do you guys regularly use lotion on your feet or maybe just on your heels to avoid dry or cracked skin on your feet, or do you just throw tape or a band-aid on it as well?

Quick clarification, I do run on the balls of my feet so I'm guessing this is from the walking I regularly do every day as well, rather than specifically caused by my running, since my heels don't often at the ground, but I'm just curious what other people do about cracked heels if they get them.
