The most comfortable shoes I have ever worn for walking. The first pair only lasted a couple of hundred miles, that was to be expected because they are so comfortable, and comfort sometimes means the soles and heels are soft and wear out quicker. But they, the left one, squeaked. It sounded like little ducklings following me down the street. I ordered a second pair when the first pair wore out and it too (the left one) squeaks, or a better word would be pops when I push off. I'm returning them and will try out a third pair. If these make noise as well I will wear them until they wear out and look for another brand for my next pair. Which is a shame since they are very, very comfortable. But the popping is very, very irritating.
