I have flat foot and normally I have a lot of pain. I started wearing these insoles in my shoes and within a few hours, the pain began lessening. The relief is very real! Now I always have a backup pair of these insoles so I will never go without again. I can walk easier and farther without resting. I am sleeping a deeper sleep now since the relief continues even when I am not on my feet. These are wonderful! I recommend wearing these to everyone who has feet!
