A nice well polished example of  leather possibly ex- military motorcycle dispatch riders  boots its a bit of a job to put a real  size on the boots as the leather is not very flexible but at a guess i personally think size 7 -8 -9 there  are some i/d mark on the top of the boot inside rib face as well as in the very bottom inside and underneath on the instep the small gusset at the rear of the boots and its folds are ok as does the poppet studs straps and small buckles.
