Query: VERY DISAPPOINTED

I was so excited after having read the reviews about these inserts because I have been living with heel pain for a couple of years, and I thought for sure these heel cups were going to be my miracle! I have never been so disappointed with a product in my life. I wish that I had set the $25 on fire and watched it burn rather than waste it on these heel cups! They have done nothing for my discomfort. I must have been sent the wrong "blue dot". I know that this happens, and that a product cannot work for everyone, but I needed to let others know that it is not necessarily the answer to your problems with your heel pain!!
