Psoriasis happens when the body's skin cells grow too rapidly and pile on top of one another, explains WebMD. It's a long-lasting condition that usually causes patches of skin to become red or silvery in color and bumpy. Eczema is another type of skin disease that usually happens when the skin becomes inflamed. Other symptoms may include red, cracked or scaly skin and blisters.

Diabetes could be another cause of itchy feet, states WebMD. It may sometimes be the first sign that an individual has diabetes and usually goes away once the disease is under control. Diabetes can also cause itching on the arms, legs or buttocks.

Athlete's foot is one of the more common causes of itchy feet, reports Healthline. It is caused by a fungus that thrives in warm, moist environments and can be spread by either contact with a person who has it or contact with a surface recently contaminated by the fungus. Itchy feet may also be caused by a hookworm infection, which leads to an itchy rash, fever, loss of appetite and other symptoms.
