Although I know Chuck's been around for what felt like an eternity, it has only a few weeks ago showed that I bought my first pair, namely the classic black (M9160). Meanwhile, other colors are gotten. The shoes are processed properly, defects have not been shown so far. Compared to normal shoes is noticeable that they are very flexible, both (of course) the substance, as well as the quite thin sole. This impression is confirmed when walking, one almost has the feeling of running barefoot. In other words: The shoes are just plain comfortable. They are among the most comfortable shoes I have ever worn. The only thing I regret not having earlier bought a pair of Chucks. ;-)
