I normally don’t buy into the miracle cures. I held off on buying from Protalus for about a year. I finally broke down and ordered two because I was tired of my feet hurting and the 100% return policy... It was an amazing difference. I could tell a large difference the first day. After a week there was almost no pain. After two weeks the pain was completely gone. I can’t say enough about how these things help my plantar fasciitis.
