I had a similar fall the other day in Double PS's. Cranked my offside turn and Stop! The ski came to a halt and my plate released. Some minor pain in my front foot and ankle, but I skiid another set and pain went in 24 hrs. Seems to me you can get hurt on any bindings. I do wonder however if that's more likely in PS's. I'm not sure. I love my PS's, not many skiers are on them in the UK, so I see more injuries in other types, Strada, Rubber. The problem is, nothing feels as "secure" on my back foot which due to a weak rear ankle, I need. It would be interesting to start a poll. Injured Foot / Ankle? Y/N. Binding? Then we can see the ratio of PS's to others. Someone else do the poll please, I don't know how to.
