How to remove callous from the bottom of my feet ?

Scrape or sand.: If very thick you can use a sharp blade to shave this down to pain. If relatively thin there are a number of devices one can purchase at the beauty supply store. Some look like microplane cheese graters and others like coarse blocks of sandpaper.
