Using a callus stone, thick foot cream and socks can help achieve smooth skin on the feet in as little as a month. There is no quick fix to achieving silky smooth feet, but the key is to remove dead skin cells and help cracked, dry skin heal by using moisturizers.
People who have dry, cracked heels or callused feet can soak their feet in warm water for a few minutes and then use a callus stone to gently exfoliate the dead skin cells. Applying a thick moisturizing cream or body butter daily to the feet immediately following exfoliation will help to trap moisture in the skin. Placing socks on the feet will help the moisturizer to soak in and within a few weeks the bottoms of the feet should be smooth and soft.
