On good boots there is a buckle instead of a ring, so you can adjust the tension the boot vamp places on your ankle and foot crown. Boots with the ring are a fashion statement. Boots like the Texas Highway Patrol motor officers use w/o a buckle/strap are custom fit, very expensive, and worth every penny. If you have not seen those particular boots, think Nazi jackboots, same pattern, both trace their histories to English cavalry boots.
You are throwing money away on harness/Dingo boots. Go to a tack shop and buy a good pair of English style hunter/jumper boots. A few hundred dollars, but they last for decades if you take care of them. Or order a set of Chippewa 17 inch rise jack boots. Steel toed, steel sole shanks. That would be THESE...
