When I purchased Protalus Insoles, I was looking for something to help with foot and knee pain from having flat feet due to fallen arches. I have to admit I was skeptical at first as I had tried others, but I was pleasantly surprised at the relief I had gotten from Protalus. I will, and have, recommended them to family members that struggle with proper insoles issues also. I am thinking of purchasing more so that I don't have to play put and take with different shoes. Try them, what do you have to lose but pain.
