I am a nurse and have had plantar faschiitis for years. I tried these early in my treatment but after 1 day I returned them. It turns out mine were 2 sizes too small; once I got the correct size, they were amazing.
I work for a doctor who has similar problems; she recommended Dansko's and had me wear her shoes for a week to give them a proper trial. Not only did my feet not hurt, but neither did my back or knees. I bought my shoes immediately and was fitted to the proper size, and now I have no problems at all. It's really incredible to feel good again. Plus I get compliments every day on how cute they are. I can't wait to try out some of the other styles to wear out dancing!
