First of all, I have washed the socks at 60 degrees and then put in the tumble dryer (gentle program) which remained stable despite the 80% proportion of cotton and socks were not included. Ever seen a big plus, since many wash socks - to survive and drying cycles. The quality is excellent, soft, not too thin, very well made, stable and comfortable to wear. Besides this beautiful anthracite is a color that can be worn on many occasions, the socks fit jeans as well as the blue suit. The fit is excellent, these parts are properly seated when two family members with shoe size 44 and 46. The toe seam is worked so extremely thin that the wearer does not feel anything. The socks are cut long enough so that the carrier must show no bare leg while seated. One of the most important aspects are the cuffs that can be really stretched really far, although the inside of the socks reinforcement is attached. Even with very large calves these socks can be worn comfortably because nothing cuts or leaves pressure marks. Of course everything has its price, which is, in my view, however justified.
