Great Quality and Stylish
Size: Large, Color: (001) Black / Black / White
Exactly what I was looking for. I don’t like socks that are no-show that your ankles rub on the shoe. These are taller than that but shorter than socks that go up and over the ankle. They’re comfortable, good quality, and pretty thick. They’re form fitting m, but not compression. I dint like compression socks, and these are tight, but not too tight.

Great for walking all day at work as well
Size: X-Large, Color: (001) Black / Black / White
I walk approximately 10 miles a day at work, in a manufacturing setting. On concrete with steel toe shoes. My feet have been begging me to change from the socks that I have worn for years. I have worn these other name brand socks for probably 10 years. So, change was obviously something I had to be pushed into. I got on Amazon and searched for training socks. I read the description. Glanced at the reviews. I decided to move forward with purchasing these. I could not have been happier. My feet began feeling better immediately. And the priced was very reasonible.
