These are simply the best socks of this style I've owned. So comfy, and so cool. The mesh-like upper area catches the breeze nicely. The fit cradles my feet like no other socks I've tried. I love these! I'm buying 20 more pairs.

--- Update! ---

However comfy, these socks are not durable. They started to fall apart a couple of weeks after purchase, and now, several weeks out, they have threads popping out all over the ankles. Not only that, after many washes, they ankles have stretched, causing them to lose a lot of their comfortability. Definitely not the worth the premium price ($8) being charged.
