I purchased an insole beginning of last yr. Used it for 6 months. I got very little better benefit from the insole I got here. My feet is flat and had heel pain. Using this shorter time helped but causes pain in the arch. I later got a professional podiatrist insole. Price is similar which was surprising. My feet doesn’t pain as much only after getting customised insole from podiatrist. I suggest if you got serious pain go to a professional place than this one as it may not be for all.
