I tried a different model of Darn tough- their 1972 light weight hiker. I actually like the fit of them more than some of their other models. I ran 15 this morning in them before work and they did better than what I'm used to for darn tough. They didn't feel clammy at all lile some of the other darn tough socks I've used which lead me to look at the merino% and I found that they are 54% nylon.
I looked at the other socks I have from them and found the models on their site. I think for me anything more than about half merino results in clammy feel on my feet. When I look at the farm to feet damascus, I see they are also a higher nylon percentage and they are 55% merino and a high percentage of nylon. It seems like for me at least that the nylon is important for dry times.
I was interested to see that all of the heavier weight socks that I love to use deer hunting were much higher merino percentage. It makes sense that they wouldn't dry as fast.
It turns out, I'm dumb!
I should have checked the tags and made sense of the weight. Midweight and heavyweight don't work for me under high exertion.
Light weight seems to do fine and is probably comparable in dry time to my regular 100% poly socks but with no stink.
You'd think that one would be intuitive but I guess I am not that smart.
