These foot files are part of the HMH Heal Your Heels program. At night, file dry (before showering) callused heels. Then, after showering, lightly apply Heal My Heels and massage in.

NOTE: Be careful not to file too much at any one sitting. Rather, file a bit each day until heels are back to normal.  Also - if you accidentally apply too much, your feet will be slippery! I apply the Heal My Heels right before going to bed. It will not transfer onto your sheets if you apply lightly and massage in well.

The files are dual grit - 180/100 and are washable. I use a nail brush and soap to scrub, then rinse well. Stand on end to dry.
