Cotton is awful. I'm hardcore wool only socks. (Well, wool blends are ok as long as it's over 70% wool.)

cotton socks, and thermals, are bullshit, bull... fuckin... shit.
but i will say that unless it's merino, fine wool, it's horrible to wear, except if you freezin better itchy than frozen
Injinji merino is the way, I agree.
Just ran with the Maro, it performed okay - gonna test on a longer run and see how it fares.
Something about 0% synthetic material is what draws me.
Btw zero itchyness from the Injinji, all merino stuff I buy is always quality with none of that drawback.
