Good quality
Size: Large, Color: (035) Steel / White / Black
These are a bit thicker then a compression sock and they come up higher on the ankle than a no-show sock normally does. They are very comfortable and soft.

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.
