Height of upper
the height of the upper ends just above ankle level.
Why wear thick socks?
Knitted with a thin plush loop material to provide comfort where you need it (heel, toes, etc.)
Seamless?
There is a special construction at the tip that makes the sock conform to the shape of the toe area perfectly.
The seam at the toe enclosure is located under the toes in the hollow area to prevent chafing on the top of the foot.
