I just got these, and I can't wait for the weather to cool off so that I can wear them!  They are true to size, well made, and fit my athletic calves.  I have 15 inch muscular calves, and the shaft of the boot is a little tight, but they'll be fine with tights, and I should also be able to wear them with my skinny jeans if I scrunch them a bit.  I ordered these in my usual size, and I did not have any trouble slipping them on.  The only problem I can find so far is that the fabric liner is not breathable the way an all-leather shaft would be.
