We bought two pair of these socks for my wife and for me (at the store), after two days there was already friction during tissue that detaches in rolls. When shopping, I still said to my wife: That's all right, if we need a few new every year, now I think they do not even keep four weeks, In any case they are already abgeribbelt that they can no longer see. A sweater that makes such 'Böbbele', I would no longer attract. Too bad.
