It sure looks like there are three on the sole that we can see. I think the real name for then is bob sole??? There would be more of them, don't you think? I agree Harlan, rough-outs low quarters (Boondocker) judging by the heel and pattern. Leggings don't work well with any other boots and the WWII style jump boot has a tapered heel and round toe. That is not a double buckle.
