These are awesome boots for the price!  But for me they do run small.  I wear a 6.5 but it was really small in these.  I almost considered getting the 7.5 they are so small.  I am really disappointed because otherwise I really liked them. The calf is generous in these as it should be in this style so they work if you need a wide calf which is cool.  Definitely give them a try but probably go on the high side of your size range.
