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.

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.
