For socks, I have decided because of the high cotton content. Unfortunately, the seller is only guaranteed to the socks, if you washed with 40 ° C. After washing at 60 ° C they have definitely lost its quality, which is why I'm not going to lower the temperature, however. The Stickeren feel sometimes a bit tight on the foot. 3 of 5 because you get quantitative lot for your money, but always with the knowledge in mind that they are not forever.
