Cool. I just ordered a pair of these ankle supports called Active Ankle T2.
They have several grades of rigid ankle support: T1, T2, and a new heavier version they call the Volt. They also have a softer, lace-up version which they claim gives more stability than taping.
The rigid series run around $45.00 apiece online, about around half that on ebay, and may be covered on certain health plans if you have a medical history of sprains or other ankle instability issues.
Very comfortable with running shoes, although it takes a wearing or two to break them in, then you can walk around wearing them all day, run, play sports whatever, but your foot is not going to roll out sideways.
I'm not going to foot launch again without them.
