Cracked Heels
By Deborah Fields, BSc (Hons), PgDip, MCIPR
Cracked heels refers to a condition produced by the occurrence of fissures in abnormally hard, dry skin over the heels of the feet. If left untreated, they may cause complications and discomfort.
In this condition, the skin around the heels is unusually thick and dry, and is known as the callus. When weight is put on the heel, the normal fat pad underlying the skin flattens out sideways to distribute the pressure more equally. However, this causes the skin to crack if it is too dry and thick.
