To relieve dry feet with cracked skin, use a daily lotion or cream that contains alpha-hydroxy acid or urea, according to About.com. Alpha-hydroxy acid sloughs off dead skin and helps to increase the retention of moisture in the skin.
If there are cracks in the skin, using lanolin may help to serve as a barrier for moisture, explains About.com. People who have sensitive skin or allergies should use hypoallergenic products or those with sensitive skin formulas. If there are rough areas on the bottom of the foot, use a pumice stone or foot file after soaking the feet or bathing, but if there is dry skin on the top, use an exfoliation product or loofah sponge. Dietary supplements can also help, including those that contain gamma-linolenic acid or alpha-linolenic acid, including walnuts, canola oil, flaxseed oil, evening primrose oil or borage oil.
Avoiding some of the causes of dry skin, such as physical stress to the feet, skin cleansers and cold weather may also help to eliminate dry, cracking skin of the feet, reports About.com. The environment inside a shoe, for instance, can get very warm and even raise to temperatures of over 120 degrees. This heat and humidity can result in the loss of water from the skin and may result in thickening of the skin. Some soaps may strip oil from the skin, also contributing to dry skin, and cold weather can cause the skin to become drier and require more care.
