My Podiatrist said the best thing you can use for plantar fasciitis is Birkenstock. So I bought some shoes & insoles. I have riding boots that I put these in & they work perfect. Have to purchase both narrow & regular for different boots. But I am very pleased with the insoles. I had a pair years ago & got rid of them. Boy did I wish I had them back. Did not realize I would have a bad 4 months with my foot. Getting better. But have to keep arch support on all the time. I tried another brand & did not feel as good as Birkenstock does.
