Dry feet with cracked heels cannot only be unsightly, but can often be a source of pain and embarrassment. Cracking or splitting of the skin causes cracked heels. This splitting may be due to dryness and/or thickening of the callus that cracks and breaks under pressure. When the skin around the heels becomes thickened or dry, it loses it's suppleness and elasticity, and can split under simple pressures such as that from walking.
Dry skin is painful and itchy, and it can allow diseases to enter the body through tiny cracks. You may see thick areas of skin on your feet, called calluses, if you wear shoes without socks or if you go often barefoot.
