The shoes I had bought in early January 2015 and also attracted the same time for 1 hour. Everything was OK :-) 2 days ago I had the shoe to 2 hours, and I walked a lot. After that I had 2 big fat blisters on both heels. Such a shoe from Camel I've never had. The clarity is an authentic left, namely he does coloring also. After tightening, I suddenly had 2 black thumb and I did not know of what. Then it dawned on me and the last thing was black, had these shoes. I have to say if I will buy again Camel, I do not know. I still have a pair of Camel which made me aware of only a bubble. Real shame about the Camel brand. I have a lot of shoes Camel and 10 years ago was just perfect each shoe as good to great. But over the years this has unfortunately taken, so I only can give a star!
