Finally found a good set again.
Size: X-Large, Color: (001) Black / Black / Castlerock
I’m picky on socks, any they always have to be Under Amour. These are top notch, super padded but also temperature regulating, feet don’t sweat when wearing, and I can tell in the winter they’ll stay the right temperature. They also fit great. Purchasing more.

Best Quality Socks & Great Thickness Plus Comfort
Size: Medium, Color: (001) Black / Black / Castlerock
I love these. They do not slip away from foot. The value for a good pack of socks was worth it. Has a good thick quality. They look clean and nice. Their stretch is good to get on and then molds to foot. Have noticed these socks have changed two times since buying. First they were slightly lighter color gray- then a darker gray but both had good quality and thickness. I am sure these are very durable but unfortunately I can not speak fully to this as the horrible steel toe shoes I have to wear rip everything apart. But if I had good shoes and everyday use of these I know they would stay good for so much longer than 6months.

Best socks ever
Size: Large, Color: (100) White / White / Mod Gray
Best athletic socks I’ve bought. I usually buy UA socks anyway and these are the best. Super soft and comfy. Fit snug and my feet don’t slide around in them.
