One of my favorite parts of my body (and there's very few of them) is my feet. It is something I take care of as much as I can and it has fast pay off as far as I can tell. My toes, sole and heels are all accounted for! That's why I'm proud to say that my heels aren't chappy, my soles don't have thick skin, and the skin on my feet are nice to touch.
I think that we should all take care of our feet. They're the farthest from our body, and sometimes we neglect them. I don't buy those expensive foot creams to keep the skin soft, I buy only drugstore products but I make sure that it does its job well.
I do this routine every night after I cleanse and moisturize my face and body.
Take a small damp towel and clean your feet all over. Its best to swipe the instep, the heels and in between the toes. If you want to disinfect your feet, its good too. Take an isoprophyl alcohol, spread the fluid on the towel and gently pat on the skin.
Leave the whole thing overnight and there you are! The first time I tried this I had to wait after 3 consecutive days for the smoothening to take effect. I had super dry, and scaly heels before, but with regular moisturizing soaks, my feet are callus free and super soft now!
Take care! :)
