Not polyester! Thank you UA!
I never realized shopping for cotton socks in 2024 would be so difficult. Luckily I found these, and all the other Under Armour cotton socks and they are the best.
I cannot wear polyester, and these only have like 1%. I didn't realize our cotton is being replaced by polyester, and I don't like it. Bath towels don't work anymore either...
I need my cotton socks and towels, I love incandescent light bulbs, I'll always have a gas powered mower and leaf blower. Also butterfinger should've never their recipe. Just sayin...

Great sock for everyday
Size: Large, Color: Black/Gray (6 Pairs)
So these are awesome but they are slightly thinner than older versions, shorter too. Just FYI if you a long time UA customer.
If you have never had their socks, I love them personally and only like one other brand better. They aren’t overly thick and they allow your feet to breath. I never have sweaty feet in these even in my warm boots. I also like that they don’t cut into my feet or get holes in the toes over long terms. The only reason I’ve thrown these out has been fraying near the ankle or someone (kids) thieving them.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.
