Input:
I am an EMT for 911 volunteer, and on a private ambulance full time. I wear these with my boots, they are very comfortable, don't disintegrate like my normal socks did when worn with the boots, and are very warm... which is great for fall/winter/early spring! But they are definitely not great for warm temperatures if your duty uniform is a heavy material as well. I am 6'2"/6'3" and these come all the way up my calves, a couple inches below the knee (so they're still comfortable when kneeling). I have been wearing these for about 8 months now (I have seven pairs) and all of them are still in amazing condition. Not much difference in thickness or feel from the first day in them.
