Do you have any great tips for heel care?!

My body is very dry.

Especially the heels, if you don't take care of them even a little bit

It's cracked and rough ㅠㅠ

I've been wearing sandals since it's summer... and my heels are starting to crack again. I usually wear sneakers a lot and always apply Vaseline before putting on socks... but since it's summer, I thought it would be okay and just went about my business, and now it looks like it's starting again.

Please let me know if you have any good tips for heel care.
