Very nice
Size: Large, Color: (100) White / White / Pitch Gray
I just received these for my son. They are very nice and look sturdy, but he hasn't worn them yet, so I cannot speak to how well they hold up in the wash or when worn. They appear to be the right size and look stretchy, but not the kind of stretchy that feels super tight on the foot (which I don't like). If they wear unusually well or poorly, I will come back and edit this.

A sock with real support and thickness!
Size: Large, Color: (001) Black / Black / Pitch Gray
I’m pretty happy with these. It seems like sock manufacturing changed 10-15 years ago, and it’s become hard to find pairs that are actually thick and durable. I bought these for an event where I knew I’d be on my feet all day, and they did not disappoint. They provided excellent support throughout the day, even while wearing shoes that typically make my feet ache after just a couple of hours. Glad to finally find a pair that feels well-made.
