The left shoe caught clearly audible already at the first wearing shortly after the march off to "clack" to. My Troubleshooting revealed that apparently one of the elements at the bottom in the production was not glued properly. I do not know where camel can produce today, but the product does not seem to be better than much cheaper from other manufacturers. On a beautiful shoe, but of the (formerly proverbial) camel-quality I'm not convinced. But kudos to Amazon, which has just promised me to take the product back.
