Great Socks
Color: (001) Black / Black / Castlerock, Size: Large
I keep ordering these over and over again. They fit well, and are soft and comfortable. My feet don't sweat like crazy while wearing them. The cupped heel makes them fit even better. They hold up to everything from everyday use to active lifestyles.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape.
My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days.
That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.

Black Under Armor Socks

They fit perfect. I bought them for my
Boyfriend & most pairs are too big or not
Really no shows like they say. If they have white ones, I will be purchasing more.
