Dry skin is also known as xerosis and occurs when the skin is lacking sufficient moisture. Dry skin is common and often occurs with ageing. Dry skin is not usually serious but it is more susceptible to cracks and splits which poses a risk for infection. The skin on the heels is naturally thicker for extra protection when walking and moving around. Dry skin on the heels can also resemble other skin conditions such as a fungal infection, eczema or psoriasis.

Symptoms
Dry skin can feel rough, scaly, flaky, tight, itchy or can lead to cracking. Cracks are more common on the bottoms of the feet as they endure body weight and friction when walking. Redness and inflammation can arise if dry skin is severe.

Causes
Dry skin can run in families but can also be caused by overbathing, cold and dry weather, sun damage and harsh soaps. Harsh soaps may contain perfumes or fragrances and those that are considered antibacterial can cause or exacerbate dry skin. After washing feet, it is important to thoroughly rinse soap from skin as leaving a residue can cause dryness. Certain medical conditions such as hypothyroidism and diabetes can lead to dry skin, as can vitamin and mineral deficiencies.

Treatment
Knowing the cause of dry heels is important for proper treatment. Keep feet clean using a mild soap and apply a rich cream containing a skin softening agent such as urea afterwards. This will help replenish needed moisture. If skin on the heels is rough or scaly, an exfoliant wash or coarse foot file can help slough off dead skin build-up. Using a humidifier at home will increase the moisture in the air during winter weather months. If dry skin becomes widespread or is bothersome, a cortisone cream can provide relief. If cracks or breaks in the skin occur as a result of dry skin, it is best to seek the advice of a medical footcare or primary care professional.
