Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions. One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.
