Great Feel and works well.
I've had a few off these.  First, I have think calves so typically the larger ones I have had came with tight rubber at the top where it fits below the knee and above the calf, and this felt like it cut-off circulation.  These do not have that feeling.  They band at the top in unrestricting but stays in place.  They allow air flow and doesn't feel like I'm overheating.  And my calf/shins feel great!
