Eczema: This sounds like eczema. It could also be psoriasis but psoriasis does not always itch.

Itchy feet: Agree with doc suggesting eczema, and possible psoriasis. Tinea pedis can occur on the dorsal foot, however the most common areas to be affected are toes and the plantar foot. Tinea pedis is less likely than contact dermatitis to be symmetrical. Psoriasis is classified as an autoimmune disorder of the skin. Are you diabetic, taking a new med?
