Many possibilities: It could be many things, including but not limited to athlete's foot, an allergic reaction, poison ivy, or severely dry skin. If needed, a skin scraping or biopsy can be taken to determine the exact cause. A prescription medication may be needed. I would suggest seeing podiatrist for further evaluation.

Have it looked at.: It could be athlete's foot, it could be a dermatitis. Before you start treating it yourself with different topical medications, see a podiatrist.
