Cracked painful heels...do you think this will work?

My heels are so dry and they keep splitting! I wear flip flops a lot, but I’m at the point where I need to fix this because it’s so painful! I’m thinking of taking some of my babies aquaphor, wrapping my heels in seran wrap and covering them with socks for the day. I’m sure there are people way more clever than me out there. Do you think this will help or should I try something else?
