@pgmoore sorry to hear that. I had a similar problem 2 years ago in which my back foot came out and my front foot stayed in. I never tore any ligaments but stretched them to the point of nearly tearing. I recently changed to reflex front and R style on the back and had a similar crash the other day to when I injured my foot, my reflex released and although my foot is a touch tender (due to the previous crash) I can still ski and my foot is fine.
I strongly feel that if I had been in and rubber boot I would have torn my ligaments again. I would agree with either going Wiley or Reflex, one extreme to the other. Reflex all the way for me, wish I had done it years ago!
