I bought a pair of these sandals probably about 5 years ago and they kept their cushion, shape and comfort the whole time.  It was time to break down and buy a new pair and this new pair, while it has the same name, is certainly not the same sandal I bought 5 years ago.  It is stiff, the cushion is less padded and frankly it is downright cheaply made.  Adidas should be ashamed to put their name on it...and for the price I paid!  Interestingly, the first sandal was made in China while the second sandal was made in Vietnam.  I wonder if changing manufacturing plants has anything to do with it.  So disappointed...
