I have plantar fasciitas and could barely walk due to the pain before I received these sandals. I wore them for a week around the house, then went to Florida to meet my daughter for a visit to Universal Studios. For the past two years I have had to rent a cart to get around the park, but this year I was able to walk the entire two days. I was tired and my legs were sore but I never had any problem with my feet with these sandals.
 It took a couple of days for me to get used to them and there was some rubbing at first where the thong portion attaches back to the shoe but after about a week of wear (which I did at home before the trip, gradually increasing the length of time I wore them each day) there were no problems. They are wide and not elegant looking at all but I don't care because I can walk again. My only complaint is that my feet tend to sweat a bit in them but that would be true with any similar product so I plan to wear a toe-less type sock with them in the future. Aside from that I love them and would definitely recommend them. I'm sure that they would not solve everyone's problems but they worked as advertised for me.
