I have plantar pain. It's miserable at times and have needed the therapy tapes, special -expensive shoes, the mornings are the absolute worse. I bought these insoles to see if they could help and I had to trim these down to fit my other shoes and I've worn them for four days now. I do notice there is more relief yesterday and today. I will continue the course. I can't expect instant results because of the problems I've had in the past were severe at times. But I do feel a difference when I'm not wearing these in my shoes!
