This is my third pair of Rainbows, before I had a pair for 8 years, and then 6 years. They're a pain to break in, but after that they're the best there is. The reason I gave 4 stars instead of 5 is because within a few weeks, the top layer started to separate in the front of the foot. Not a huge deal, as I was able to shoe glue it back together perfectly. This has never happened before, but I would expect flip flops that cost this much to be a little sturdier in that sense.
