Is this a troll thread?
Merino wool socks are pretty much the absolute best things you can have on your feet. They wick away moisture and are antibacterial making sure you feet never ever smell (unless you'r covering your feet in fish guts or something weird).
The merino fibers are super long and soft causing them to not itch.
I pretty much only wear smartwool phd socks now cause of how amazing and comfortable they are.
Old school wool socks.. yeah, those might be itchy.
