Although I don't think the shaft is 19.5, they fall pretty much the same place all my boots do, just below my knee cap.  These run 1/2 size big Im a 10 and had room to spare in the calf and foot..which is unusual. Im usually a tight fit on shaft.  The suede and boot look good as far as quality goes. The price cant be beat, I've seen faux suede at zappos/6pm/shoes.com for over $80- insane I don't buy fake leather/suede! these are awesome for 40+$ kudos to amazon!
