Not a scientific or comprehensive test, but 4 years ago I tested most of the top brands of socks and liners. For me, it was hands down, Darn Tough Socks with no liners.

4 years later, I have yet to send a pair back due to wear and tear.

I am involved in a project in Andes Mountains where my boots and socks have to perform.

I use the COOLMAX® BOOT SOCK FULL CUSHION. I have had zero issues with these socks.
