What are some problems with dry foot skin?

Health problems that can cause dry skin on the feet include athlete's foot and diabetes, reports WebMD. Athlete's foot is characterized by peeling, cracking and blistering of the skin. Diabetes may cause foot skin to be rough, scaly and flaky.

There are three types of athlete's foot: interdigital, vesicular and moccasin. Interdigital is the most common type of athlete's foot and it usually occurs between the smallest toes, according to WebMD. Itching, scaliness and burning are the major signs of this type of athlete's foot.

With vesicular athlete's foot, there is an outbreak of blisters filled with fluid under the skin on the bottom of the foot. Sometimes the blisters also appear on the heel or the top of the foot. However, this type of athlete's foot is not common, states WebMD.

A moccasin infection causes minor skin irritations that start out itchy or dry, states WebMD. After a while, the skin begins to thicken and eventually cracks. The rash can occur on just the sole of the feet or may cover the sides of the feet as well.

Symptoms of diabetes-related dry skin foot problems include grayish skin, redness or itchiness, states the National Diabetes Information Clearinghouse. For people with diabetes, dry skin may be due to nerve damage, high blood glucose or poor blood flow.
