If you have plantar fasciitis, Achilles tendonitis, ankle strain, arch pain, this may be just the thing for you! 

Promising review: “I came down with a great case of plantar fasciitis, and a friend who is physical therapist said ‘It’s about stretching out that calf muscle!’ Rather than go through the usual stretching contortions in the hope of focusing in on the calves, I started looking at these kinds of devices. All I can say is: This one is easy to use and is also good for hamstrings and other potentially troublesome muscles that need stretching in order to avoid problems (especially as one ages…). I used it daily and my plantar troubles were gone within a couple of weeks. I don’t know if other such devices work better, but this one gets a 100% rating from this aging being.” —Honest American Reviewer
