The shaft is too high for me (I'm 5') and when I sit down, the back of the boot digs into the area behind me knee. Also, because my calves are lower than average because of my height, the calves of the boots don't match up to mine and wind up being too tight with the ankles too loose. I also recommend sizing up in the foot. Most boots I've found run a size smaller than flats and heels and these are no exception. I usually wear a 6 and got these in a 7. The foot fit well.
