Low quality socks.
Size: Large, Color: (001) Black / Black / Castlerock
I have been buying Under Armour undergarments for years and have noticed a steady decline in quality. These socks are no different. I purchased another six packs of very similar styled Under Armour socks in 2023 and recently they have started wearing out. Those socks are no longer available for reorder, but these extremely similar socks were so I ordered them. The quality difference is obvious just by looking at and feeling them. They are more of a faded black/brown than the black pictured or the black that the three year old socks still are. The material is completely different and feels lighter. When wearing them they already feel like they are bunching up in my shoes, which the old ones never did. I do not expect these to last even a year and will not buy them again.

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.

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.
