I have developed planter fasciitis, plus I have a heel spur that bothers me every now and then. I did some research about the best insoles for my problem and found out that these ones are on the top 3. I didn’t put them in my shoes yet, but I stood on them to see if they were the right size… and could feel the difference. My arch rests well, my heels are relieved and my problem seemed to disappear. SUPER RECOMMENDED!
