I was having a hard time deciding between smartwool and Darn Tough (DT). had a few pairs of both. the smartwool wear out much quicker. They may have been better in hot humid conditions, but I could never really make up my mind on that. At first I did not like the feel of the DT as much. but it grew on me. I actually prefer it now and have bought enough that it is the only sock I wear now unless I am really dressing up.
