After the very first day (unwashed) were my feet black with adhesive lint, disgusting.
After the first wash (40 °) and the dryer / dryer were all strongly verfusselt all socks, angefranst on the edge and not very presentable. Possibly one reason for the extreme lint on the dryer, but with my other socks (not, unfortunately, be ordered from Amazon) takes the process of decay with the same care much slower.
Now I also realized after repeated washing, the color black has fallen sharply, and is now more likely to be described as gray-black.
Conclusion: I buy these socks will never and can not recommend it.
