I have worn thongs for years since I live in California and my feet get too hot to wear shoes. I love FitFlops for their general comfort EXCEPT for the right foot. The thong part that goes between my toes is built consistently off on that shoe. I have four pairs--two bought last year and two for this year. Each pair causes the same problem. Last year, I got a blister between my big toe and second toe where the thong part goes and finally I got a thick callous. This year, it's actually causing arthritis in my right foot. I continue to wear them because they were not cheap and I have not bought any other thongs. I do like the thick sole. I now have to alternate them with tennis shoes, though, in spite of having such hot feet. I'm trying to reduce the arthritis pain and swelling on the top part of my right foot. This has never happened with any other thong. Do other people suffer the same problem with these shoes?

The other thing I want to mention is that they do NOT exercise anything. They do not cause any fitness to occur. I have a condition (perhaps fibromyalgia--it's undiagnosed) where I get terribly sore whenever I do any exercise and these so-called "Fit" flops have never caused an iota of soreness in any of my muscles. So if there is a degree of fitness, it's a VERY slight one. I wear them because they are thick soled for walking on the uneven surfaces where I work, I can stand up at my desk in them on a concrete floor, and they are cool in the warm weather we have in California. Supposedly, thick-soled rubber shoes are easier on joints.
