Joe,
If I may introduce a different point of view:
Weak ankles are in part
because of "bomb proof boots". People get used to coddling their ankles all the time with unnecessary external support, while the muscles atrophy and the become inflexible.
I found this to be personally true for me. I had a job that required me to wear heavy work boots (8" uppers) for a few years, laced up with steel toes and heavy soles. I noticed after a couple of years that not only did my calves atrophy and my ankles weakened a bit even though I was still on my feet on the site for as much as 12 hours a day. My pedometer tells me that I walk about 10 miles a day when working on site. Doubtful - maybe on a large site with a lot of material hauling. Personally, I think it is much closer to 5 maybe 7 - tops on the average day.
In my job as a nature photographer, I do lots of hiking, a lot of it off-trail over challenging terrain. I do it mostly barefoot, and occasionally in light sandals – never in boots. I've never had an ankle injury, because my ankles are strong and flexible, because I use them, and don't coddle them and over-protect them.
Not being judgmental about that, but I personally won't expose myself to unnecessary risks of stepping on thorns, cactus, broken limestone chips, agarita bushes, fire ants, wood ants, scopions, snakes, consequences from a misplaced footstep, or any of the other things that line just about every inch of trail here in South Texas. If I was walking on fields of clover, I would be right there with you!
Ankle support and arch support are fine for people with substantial pre-existing foot problems, but relying on them all the time for regular hiking is unnecessary, weird, and counter-productive. Nature or God gave you feet that are quite capable of being used as they are. Belief in the need for footwear is F.U.D.
We'll see. You may be one of the lucky few. But as my feet get older, they appreciate all the help I give them.
The most effective way to work your ankles is to use them regularly (in unsupported hiking), not to do occasional exercises for a few minutes in the weeks leading up to a big hike.
Now that, I absolutely couldn't agree with more.:thumbup::thumbup:
"Bomb proof" boots also lead to ankle injuries in other ways. They lead people to pay less attention to where or how they step, relying on their footwear to protect them. They also disallow the boot wearer to feel the ground with their feet. People who rely too much on their footwear often don't learn how to walk well, and they are thus more prone to injury.
For people who want to strengthen their ankles and reduce the risk of injury: start walking and hiking regularly, without relying on being over-shod.
Once again, I agree 100%.
