I have low-cut, thin merino socks for the summer, but most wear sandals. In the winter I have a bunch of thicker calf-height merino socks for winter boots or sneakers, and dedicated over-the-calf socks for skiing.

My brands are whatever merino is the cheapest at the time on Steep and Cheap, EMS, or whatever. I have Darn Tough, Fitsok, Icebreaker, Smartwool. Probably 20 pairs in total from the last 20 years.

The EMS socks have lasted the longest, Smartwool the shortest.
