I tested 2 pairs of socks along with Darn Tough socks and they have lived up to their name! I wore each pair for one month washing them each night, as you can see in the image the Darn Tough has held up nicely compared to normal socks. I wore these guiding and working out every day with 3-7 miles of walking / running on them. My normal socks have gotten thin in the high wear areas and are coming apart. I also have worn the heavy weight version of this sock when the temps have dropped and they work great! I highly recommend these socks for every day wear to running / jogging as well as work. I have been very pleased with how they have held up and lasted.
