The best athletic socks you can buy!
Size: X-Large, Color: White/Graphite (6-pairs)
These are the very best athletic socks you can buy period. I have had several pairs that are over 10 years old and still in wearable condition. We are talking several hundred washes. They are super comfortable and no show. I can't overstate how great these socks are.

I hate wearing any other type of socks anymore because you get fluid and my legs and these don't cut into my ankles they're very comfortable

Repurchased many times. My husband's "everything" socks!
Size: X-Large, Color: White/Graphite (6-pairs)
My husband always asks for a new pack of these UA socks every birthday and Christmas. He wears them with all types of shoes and for everything he does: daily work, weekend casual, and athletics. They're thick, super soft, and durable, but yet still breathable--even in the heat of summer. It takes months and months of constant wear and washings before they develop holes in the heel. Great socks!

Great socks
Size: X-Large, Color: White/Graphite (6-pairs)
I really like these socks. Feel good, long lasting, high quality. Fortunately they are not as high at the ankle as they look in the picture.

Very Nice Athletic Socks - Fit as expected.
Size: X-Large, Color: Black/Graphite (6-pairs)
So far so good. I purchased the XL size and they fit well for my size 14 feet. They seem to have held up well in the 7 days I have been wearing them - 2 washes so far. Only time will tell if they last. I do know if you walk around the house in your socks they will develop holes on the bottom much faster than if you just wear them in shoes.
