I started with the ankle version of this model socks.  These fit and wear just like the ankle version.  Fairly tight, but still loose enough so you can wiggle your toes.  A bit thin, but they've yet to tear or show any signs of giving up.  They remain cool even while wearing boots on a very hot day.  On the other end, these don't do a great job at keeping your feet warm on a cool day.
Beyond that, I love these socks.  I wear these when I'm wearing work boot as well as simple every day boots and sneakers.  They're thick enough at to not allow my boot to dig into my calf, but also thin to enough to allow for breathing.

These basically feel like dress socks, but are a bit thicker and quite comfy.
