High heels, poorly fitting shoes, extensive workouts in the wrong shoes and excessive friction are all causes of foot discomfort. Pay closer attention in these situations to prevent problems.
Make sure you are giving your feet the proper care. If after a night of dancing or a particularly strenuous workout your feet still hurt, soak them in Sally Hansen Revitalizing Foot Soak. Follow with Sally Hansen Pumice Foot Polish and Sally Hansen Moisturizing Foot Creme.
If you are still in pain you should see a physician.
