Supplement 30.10.2013:
After two weeks, there were increasing cracks under the sole (especially the heel), has so Amazon withdrawn shoes and sent me new. Interestingly, the new 0.7 cm shorter (sole length) and fit perfectly. The first were made in the second Vietnam in China. (This means that the various assessments of the size explain in the comments: The China version runs one size larger, corresponding to the specified size shoes from Vietnam ... at least with my two pairs.)
Now if you could keep the soles, I am completely satisfied!
