Good article. My massage therapist taught me this. I use a wooden rolling pin along with a tennis ball. Gotta take care of the feet! He also taught me trigger points to release the achilles - remembering a YouTube I watched as well. I'll see if I can find it again. The key is to never get the heel pain in the first place... meaning if you're stretching like you're suppose to after a run... ;) you get it.
Ease heel & arch pain. (The achilles tendon attaches to the calf muscles. Stretching these structures will decrease the pressure to the heel and have less pull on the arch.) Hold each stretch for 30 seconds and repeat 3 times per day and after training. Do the stretches everyday.
