I purchased these sandals for plantar fasciitis pain in my heel.  Upon their arrival, I was pleased with the style and obvious quality, but I was disappointed when I put them on.  I have found that shoes with good arch support and a "cushy" heel are best to relieve my heel pain.  While these have great arch support, the insole feels like it is made of a harder plastic-type material instead of soft rubber.  I know you are supposed to break these in slowly (only wearing a few hours at a time at first), but I don't foresee these ever being my choice to wear to an outing where there is a lot of walking involved.  It isn't quite flip-flop season where I live, but if my opinion changes about that, I will update my review.  (I normally wear a woman's size 8 tennis shoe -or size 9 if it's Nike brand - and with these I ordered 7.5 and they fit perfectly.
