Great everyday socks

Fit well and very comfortable. They keep the feet dry throughout the workday.

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.

I bought these originally at my local UA store and had to buy more. They are my favorite daily wear.
