Great socks

Great socks. Very comfortable. Use these socks for work. I walk up to 10 miles in 8 hours at work and these socks stay soft and in place when I get home

Super Comfortable and Great Quality!
Size: Medium, Color: (001) Black / Black / White
These Under Armour socks are hands down some of the best I’ve ever worn. They are incredibly soft, breathable, and provide just the right amount of cushioning for all-day comfort. Whether I’m working out, running errands, or just lounging around, they feel great on my feet.
The fit is perfect—not too tight, but snug enough to stay in place without slipping down. Plus, they hold up well after multiple washes without losing their shape or softness.
If you’re looking for high-quality, comfortable socks that feel amazing to wear, these are definitely worth it. Highly recommend!

Good sock, size is a little big
Size: Large, Color: (100) White / White / Black, Size: Large, Color: (100) White / White / Black
Good quality material and fairly thick. Size large for a 9.5 shoe is a little big for the foot portion as the heel sits too high but the overall length is good.
