What is"smart wool"? I don't know.
what i do know is that after a 2-3 months the padding in these socks is gone and they are hot! I tried a pair of merino wool socks even in the summer of 2018 which were way more comfortable, cooler, better wicking, and far more comfortable. i replaced all these with merino wool which is more expensive but i don't like being in pain from cheap, gimmicky socks.
