brace / support ankle options?

Up until two years ago I practiced walking with a regular walker and used an afo on my left leg, my right leg is strong enough for no brace. Two years ago I started using a up n free gait trainer that has a bicycle seat and piston that help support me while I walk. So I've been walking with no right or left ankle support for two years and my ankle seems to have been fine. I recently started using a easy stand glider and my left ankle has been hurting, so when I was walking now my left foot kinda turns in and my ankle out and gets soar after a while. That foot won't plant very flat. So I went back to my afo for safety and it works ok. But was wondering if something simpler that was less restrictive. There are so many options out there, here are a few I've come across, please share your thoughts.
