If you actually suffer from Plantar Fasciitis, then these are the sandal for you.  Living in Florida means you wear sandals most of the time. After wearing these for two weeks, my heel pain is gone and I haven't had to wear my boot to bed once. I wear them from morning until night; the soles are firm (not hard as a rock) and the support is fantastic. I debated whether to spend so much money on a pair of sandals and after reading some of the other reviews almost decided against it.  Then one night in desperation I decided to purchase a pair, these are the only sandals I will ever wear. Yes, you may get a blister, so put a blister patch on it, it will go away.  Yes, they are heavier than a flip-flop, but they have the support needed for this type ailment. It does take a week or so to get use to them, but it is so worth it. Like I said in the beginning, IF you suffer from Plantar Fasciitis, this is the sandal for you.  If you don't suffer, then what are you looking at these for?
