Hello there.... I went through your query..... I can understand your concern..... Its quite common in this winter season..... Soak your feet in warm water for about 15-20 minutes. Rinse and pat dry...Mix one teaspoon of Vaseline and a few drops of lemon juice. Rub this mixture over your heels and other cracked parts of the feet till it gets absorbed into the skin....Apply this mixture and wear a pair of woolen socks... I Hope this helps.....
