My heels are horrible because I am always bare foot. I use Johnson’s foot soap and soak them in really warm water for about 20-30 minutes. Then I have the scraper thing and I scrape them really good. I use a blue one that is triangle shape. One size is medium and one side is larger and one size is a smoother. After I do the soaking/scrapping thing, I smother them in lotion and put on sox. I let them soak in the lotion all night. They aren’t perfect but they are a hell of a lot better than when i started.
