Very comfy
Size: X-Large, Color: White
I'm a size US Mens 14 with huge calves. Finding comfortable crew socks can be somewhat difficult.
These are extremely comfortable, very stretchy and soft. Very worth the price.

These socks are just OK. One arrived with a hole (easily sewn up, but kind of bummed about that). I prefer the Under Armour Resistor socks - they have support built into the socks that you actually can feel, and they were same price for 6 pairs!
