I have 1 weak (previously injured) ankle that rolls inward and sprains easier than it should.
I've been using NB 504 trail running shoes - with a flared heels, a plastic stabilizing "horseshoe" running between the sole and the heel of the shoe, and enough non-stretch fabric that my fore-foot doesn't slide sideways and my heel stays in the heel cup.

Do any other low-top trail running shoes or features stabilize the ankle better than these ?

Also, are there any exercises I can do to make my ankle more resistant to rolling inward ? I suspect this may be the answer, since the trail runners work fine for my other ankle - but toe raises don't seem to be strengthening my ankle, just my calves...

I had a nearly broken ankle at one time. The rehab I was told to do was to get a rubbermaid, fill with sand, and write the alphabet deeply into the sand with my toes over and over. What a workout! Still, I have to wear real boots while others skip around in their slippers.

I have walking techniques to avoid sprains as well. My ankle goes so that the outside face is toward the ground, so on sketchy terrain etc, I consciously separate my feet by a wider distance laterally. Or, turn my feet outward extra, duck footed. Part of my problem is being very bowlegged, so I tend to get my feet crossing over my center of gravity on downhills if not careful.

The original Aircast is something I want to try out with little bitty shoes, my bro played soccer in one for a while.
Good luck with it!
