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
