The newest fad in foot health is an electric pumice stone or a callus remover.  These are very effective if you do not have any diabetes or lack of sensation.  Just be careful that you do not cut yourself with it or take off too much skin.  As well this is not recommended for those that have neuropathy or lack of feeling on your feet as it could easily cause a sore or ulceration.
