Hmm, I get why you might think that. It's like the "gaming" tag in equipment or something similar. Not to get too controversial with the answer, I'll stick to socks. Darn Tought take their tactical line as no joke, their tactical line goes through testing and some specific procedures which I can't remember from top of my head. I think that the two pairs which I own from Darn Tought are indeed from their Tactical line. Tactical line is different in terms of some qualities which other lines aren't as focused on. Of course they need to be well made, reinforced and I think are more elastic than the other lines. I knew all the advantages of the tactical line when I was making my choice, however now I forgot most of it. If I find the info I will post it here. But what is a fact and something which I have checked is that their tactical line is indeed different than other lines. If I am not mistaken their tactical line is actually used and made for military, firefighters etc. so that means that the sock needs to be comfortable, that it stays in place (i believe the tactical line has better "grip" and is kind of more snug so it never falls down), and needs to keep the ventilation in the foot. I own a OTC Extra cushion, which is... you could walk in Russia with these.. the cushion is CRAZY, they are super thick.. made for the coldest weather. I also own a Mid-Calf light cushion.
I am very happy to hear that you appreciate my post! I'll check out the two brands which you mentioned. I hope you enjoy your Tactical socks, did you re-discover Darn Tough or did my post help you with that and inspired you to order them hahaha?
