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.

Much much better than the standard sock
Size: X-Large, Color: (001) Black / Black / Castlerock
These socks are superb. Lots of padding in the right places, snug where it should be snug & loose where you don't want it to bind. They are marked with an 'L' for left foot, & 'R' for the right foot (it makes a difference in the fit being perfect. They stay up on your heel & don't slide down

4 lefts vs 2 rights
Size: Medium, Color: (001) Black / Black / Castlerock, Size: Medium, Color: (001) Black / Black / Castlerock
I ordered a set of three. I ended up with four left socks and two right socks lol. Granted it doesn’t matter unless you’re OCD. JEEZ. Love the socks but not the attention to detail the sock company did on matching left/right marked socks.
