1. Sit in a chair, and place your affected foot on a towel on a hard floor (not a floor with carpet).
2. Scrunch the towel toward you with your toes. Then use your toes to push the towel back into place.
3. Repeat 8 to 12 times.
4. It's a good idea to repeat these steps with your other foot.

Make this exercise more challenging by placing a weighted object, such as a soup can, on the other end of the towel.
