So far, these seem to be very high quality socks. Very comfortable. Cushioning is soft. Fabric is thick but not bulky. Doesn't slide down. Elastic is supportive but doesn't choke the calf. The fit of the heel is slightly on the baggy side, but better than many work socks I have tried. (as a point of reference I wear a Mens 8 US).
I will be buying more of these.
