This is the easiest review I've ever written. It's simple. Without the Samurai insoles, my heel hurts so bad I limp when I walk. When I wear the insoles, I have no pain. I don't even have to take ibuprofen. I highly recommend going through the break-in process as my arches were a bit sore the first week. Since then, they are the only thing that keeps pain at bay. If I go on a dog walk without them, I'm hurting by the time I come home. Absolutely the best $30 I've ever spent!
