Is there a rash
or other problem there? If there isn't, sometimes dry skin
is the problem, and you can use a non-allergenic moisturizing lotion on your feet.
Sometimes a foot powder will help too. If there is a rash, or there is pain, discharge, or a lot of swelling, you should see a doctor. Also, if you are a diabetic, you should see a doctor about problems with your feet, no matter how small.
