I ordered these for my son, he’s in the military and the socks they issued him were all getting holes worn in the top of the toe area from his work boots. So I ordered him some of these to supplement his normal ones. He said they’re pretty comfortable, we’ll see how they hold up after he wears them for awhile. But initially I’d say they’re a good buy. Points for the affordability.

New Socks (Finally)

Color: Green, 4 Pack, Size: Large

I haven’t treated myself to new boot socks in WAY too long and all my old ones were starting to get holes in them, so I figured it was time. These were easily the best deal, being really soft and comfortable for a decent price. Hopefully they last a long time!

Comfortable, solid sock

Color: Green, 4 Pack, Size: Large

Out of all the military socks I've worn, these are the best. Super comfortable, not that thick heavy material you normally see. These will be my go to from now on. My only gripe is that as a taller person, these socks only go halfway up my calf, but thats a marginal complaint. Definitely get these if you wear these types of socks a lot.
