..and they're perfect!  I'm average build and have pretty muscular calves so I was afraid they would be too tight, but the fit was just right.  I was even able to tuck my pants in.
I got the red boots and the color is so vibrant.  It's not superman boots red, so no need to worry.
The only minus I can think of is that when your feet sweat, the boots make "fartsy" noises.
