Plantar Fascia Towel stretch

DescriptionThis exercise is aimed at stretching the plantar fascia. To begin place a towel around the ball of the affected foot, keep your heel in contact with the ground and avoid bending your knee. Pull the towel toward you until you feel the stretch in the bottom of your foot and back of your calf muscle. Hold the stretch for 20 seconds and repeat 3 times with a small rest period between stretches. It is particularly useful to perform the stretch first thing in the morning or after a period of rest.

Looks like a winner. I wonder will this stretch also stretch the muscles around the heel bone?
