Good hiking socks

Did the socks now tried on several days of hiking and have to say that they sit perfectly. So far, they do not slip in the shoe and keep the foot dry and comfortable. From me, therefore, a strong buy recommendation, especially here for 20 Euro four pair are supplied.
But pay attention urgently that the socks (as described in the manual) are washed before wearing. I have not done namely the first couple and they were very slippery in the shoe. After washing, then the described very good hold on the foot.
