To me, the feet are some of the most important parts of your body that you must take care of. Do to my problem of having "flat feet, " I developed a sharp pain in my left ankle about two months ago that was preventing me from completing my weekly fitness regimen. My orthopedic surgeon injected cortisone into my ankle but the x-rays indicated that my bone on bone pain was due to the flat feet that had severely impacted my ankle biomechanics. The Good Feet system is not cheap but it was worth every penny to me as it restored the proper arch and foot biomechanics that eliminated my pain (almost an 8 level) and restored my overall balance. In fact, I went directly to my Zumba class to test out the orthotics provided by Good Feet. This would have been impossible without the orthotics provided by Good Feet. For the record, I am 68 years young and the orthotics have really helped with maintaining my quality of life and fitness.
