Based on other reviews, I was going to size down, but the half size down was sold out.  So I ordered my typical size.  The boot fits fine with perhaps a little extra length, but it is definitely not too big.  The shaft of the boot has plenty of room to stuff your jeans into.  Although there is no zipper, these are very easy to pull up onto your foot and over your calf.  The boot comes up to just under the knee.  The material is a synthetic microsuede.  I ordered the grey--a very nice dark shade.  The insole is flat and does not offer much in the way of support.  They are fine for wear around an office, but I don't recommend wearing if you are going to be on your feet all day.  Ultimately a very cute boot, and I am pleased with the purchase.
