I've used a taping method for years that is not supportive but does prevent further damage through turning the ankle.
Its a proprioceptive (position sense) aid - i.e. it helps you feel the turn coming early and allows you to react before the ankle has gone too far or reached a weak point.
I'll try to describe:
start with the tape on the ball of your foot, or possibly slightly off the back of the ball.
run it diagonally back across the sole of your foot to come up on the outside of your foot just infront of the ankle bone.
run it across the ankle bone and carry on diagonally across the achilles / lower calf.
keep it coming up and round to end on the inside of the calf about 1/3 of the way up.
In effect you are running a spiral from ball of foot over outside of anle bone and up to the inside of the calf.
You need to practise getting the position of the ankle right so that the ankle can move free. ( I tend to turn my ankle out a little.)
I know this works through proprioception and not physical support because when I put the tape on and run / race I can often end up with the tape torn, - so no support available, but I have never ever turned an ankle whilst wearing it.
I actually think I could get away with just wrapping the tape across the back of my calf.
I think this approach works as it protects from further damage but allows the ankle to do all its usual work and so to build and recover propoerly
