What causes dry skin?
The reason many suffer from dry feet is that the skin on the feet, especially on the soles, has fewer oil glands than elsewhere on the body, making it more susceptible to being dehydrated and dry. Therefore, the skin on the feet needs moisture to keep it supple.
In addition, the lack of moisture can worsen by other factors such as ill-fitting shoes, heat and humidity inside shoes, bathing in very hot water, certain soaps, and cold weather which all can draw moisture from the skin. Aging is an underlying factor to dry skin since when aging the skin produces less oil which impairs its ability to retain water making the skin dry.
Other dry feet causes are athlete’s foot, eczema, psoriasis, diabetes, and other medical conditions which can also lead to skin dryness on the feet.
