I have def noticed some improvement so far in my plantar fasciitis, and I hope by continuing to use the device I will see further improvement. I have had severe pain in my heel for 9 months, and although still painful, I am noticing my symptoms are less severe. If I could suggest one design modification, it would be to round the edges of the two front screw points, as they dig in to the underside of my foot when I am wearing it. At the moment, I wear it back to front to avoid the painful digging in of those edges. Other than that, I am pleased with the device and would recommend it’s use to others.
