Wait a second, how can a tennis shoe even help to prevent an ankle roll in the first place? I can only see this if you're wearing high tops that serve as a brace both above and below the ankle joint. Almost like a splint, this would truly prevent ankle roll. However, in a tennis sneaker, the ankle is exposed, like in any other sneaker. It shouldn't matter how stiff the sneaker is. In theory, if you wore steel sneakers with the ankles exposed, how would that help prevent rolling the ankle? If you stop short laterally, the entire steel shoe can just roll right over at the exposed ankle hinge. Now that I've given it more than 30 seconds of thought, I think I was suckered into yet another marketing scam. "Tennis sneakers prevent ankle roll". I say BS because it makes no sense. My old Prince sneakers were beat up, so it's not a total loss, but I'm just saying. At least the new Barricade 6.0's will have fresh padding. But, I can't see how they can help prevent ankle rolls.
