Does anyone know if our insurance as drivers cover these? I went in to try some on today, and they seemed pretty nice. I did not purchase any because I wanted to see if they are covered by our insurance. If anyone uses them, did you experience any pain relief? I have a sore knee bug me every once in a while, along with an ankle. The salesman made a good pitch in that it would help me out, but the price tag was a little steep.
