For the price these are unbeatable.  Extremely comfortable, yet cute.  Versatile look.  Quality looks good.
I would say that (at least in size 10) the calf is bigger than I expected.  I have larger calves (16 inches) so for me this is great - even over jeans they work and aren't too tight. If you have narrower than average calves they will be too big.
I am 5'6" and did not find the shaft height too high or at all uncomfortable. If anything I'd prefer it 1" higher.
