What causes skun under toes to crack?how fix?thankyou

Athlete's foot: Usually, cracked skin under toes is a sign of a fungal infection, also known as athlete's foot. Often times this is seen with feet that are too warm and sweaty. Try using an antifungal spray (over the counter), change socks when feet become damp or wear sandals and expose feet to air. Spray inside of shoes with antifungal spray and set shoes out in sun to dry out when not wearing.

Most : Of the time its due to a fungal infection like tenia pedis. Try otc products and keep shoes dry and dry really well after bathing. Make sure socks are clean and dry.

To start with...: It may be athlete's foot. The best otc medication (in my opinion) is lotrimin (clotrimazole) ultra. Socks should be a synthetic material like those manufactured by thorlo [http://www.Thorlo.Com/]. Dilute vinegar soaks are good as well. Dry the inside of your shoes by placing them up-side down over an air return vent at home overnight. If this doesn't make things better in a couple days, see a podiatrist.
