I do a lot of hiking as well as running, and I'd hesitate to do a run, even on rough terrain, in hiking boots. They'd provide plenty of ankle support and traction, but it would also be the equivalent of running with ankle weights, and would put a lot of extra stress on your lower leg joints. Not to mention that they'd also keep your feet and ankles from flexing normally during a run.
