I couldn't face any type or kind of exercise whatsoever because my feet hurt so badly. I had to sleep with ice packs on my feet just to make it to the next day of work. For years I just hung in there, saving my feet for my work. Then I found the heel cord box, and I was able to heal my feet and the whole world has opened up for me. I can now do the treadmill for an hour and keep going through my day without any pain. It's like getting a whole new life.
