After injuring my feet playing basketball wearing the wrong footwear, I was diagnosed with Plantar Fasciitis. Not wanting to spend hundreds on custom inserts thought I would try these Protalus inserts out. I read the reviews how people got instant relief and were out running marathons. That was not my case. I got the first generation inserts, and I could tell they were helping, but no miracle cure. Since they were helping some, I decided to get a second pair for my other shoes. I got a pair of the new inserts. The first few days my feet hurt something horrible. The instructions that came with the new insoles said this could happen. However, after a few days, my feet adjusted to them, and the pain went away. Now a few weeks later I find that my feet are doing so much much better. My Plantar Fasciitis is causing me less and less discomfort every day. Still no miracle cure, but the inserts have made a remarkable difference in just a few weeks. If you have Plantar Fasciitis give the inserts a try. They are well worth the small cost.
