Lasts a while for the price
Number of Items: 6, Color: White (6-pairs), Size: Large
Honestly, the best quality socks for the price. Last a long time and lots of sport and non-sport usage. Trim your toe nails though, this isn't immune to dank toe nail care.

Great Quality Socks!
Number of Items: 6, Color: Black (6-pairs), Size: Large
These Under Armour no-show socks are perfect—comfortable, breathable, and they stay in place all day without slipping. The fabric feels durable yet lightweight, and they wash up nicely without shrinking. Great value for a 6-pack, and they fit true to size. Exactly what I needed!

Good for a few uses
Number of Items: 6, Color: Steel Assorted (6-pairs), Size: Large
Elastic breaks down after a few washes and they become "quitters" and slide down into your sneaker. Very soft and comfortable for maybe a dozen wears

good socks
Number of Items: 6, Color: Red Assorted (6-pairs), Size: Large
I like that they stay on pretty well. also liked the thickness - not too thin / not to thick. also i like that on the inside there are no random threads all over ... i found that to be a problem in similarly priced products from other major brands (and also the cheap options at costco also had that same issue). I've had them a few months and I think they'll last. *** 1 year Update *** Still great! I think they'll easily last me 2-3 yrs! Love how comfy they are. easy to pull on / off. nice colors. highly recommend. I bought some road runner sports socks for almost 5X the price at the same time i got these and while the road runner socks are pretty good for sports (they fit tighter so tend to stay on in active mode), i find these under armour socks much more comfy for daily wear.
