Effective creams for treating cracked feet include medicated 40-percent urea creams such as Flexitol, Urix or Carmol, according to the Skin Center. Deep moisturizers that are nutrient-rich, have a heavy consistency and exfoliate are generally used for the treatment of extremely dry skin.
Dry, cracked heels not only need exfoliation to remove the dead skin, but also a gentle solvent to soften the feet, as well as a lubricant to keep the skin supple and moisturized, states the Skin Center. Do-it-yourself methods from Fun Times Guide suggests using olive oil, sea salt or lavender oil to achieve these results. Cracked feet with deep fissures can lead to infection and are often a sign of an underlying health issue, notes the Skin Center, and need to be inspected by a doctor for other treatments.
