Ok so I have big calves (17 inches around at the largest part) and these actually fit me with no problems putting them on, and go all the way up to my knee.  They are thin and are more for maybe spring, summer, or fall, but if you're wearing these under pants then they will still work out ok.  If your calves are bigger than say, maybe 21 inches, then you may have a little trouble.

ADD:  These seem to nick easily.  While I was pulling them up my ring slid against them and caught a thread.  So be kind of be careful
