Fahgetaboutit. The big, heavy, unbreathable hiking boots are unnecessary when backpacking with a light load.
Tennis shoes are the way to go. They are light and breathable and they dry quickly. The US Army, and you KNOW you can trust them, ha,ha, did a study and learned that every pound of weight one carries in their shoes equals 6 pounds on the back.
I can attest to the difference in speed and agility. I have a pair of hiking boots. Not the huge clumpers, but high top boots. They are heavy and I do clomp in them. In my tennis shoes, I can walk farther without fatiguing so fast, and they breath so my feet don't sweat so much, and I haven't even had an inkling of a blister, though the shoes are new.
As for ankle reinforcement, just a wrap of athletic tape does the trick, and, it's breathable and can be replaced.
Such a deal!
