Last year Sept.30 second pass in first set of day hit shore backwash immediately after ball 3 and went OTF. 34 MPH and 32 OFF. Came out of rear boot and partially out of front. Lower laces were snug (bungee not stretched) and I had heard about over tightening problems on upper so I pulled keeper all the way to end and put a knot about 3" down from keeper, they were loose. I always soaped my feet. My mistake was having a toe lift under the intuition liner, between the liner and the shell. It was there so I would load the front of my ski quicker and also level my foot position because I had superfeet in the front boot. In my opinion never put anything under the intuition liner. It took a plate and 13 screws to put my tibia and ankle back together, on crutches four months.
Never put anything under the liner. They always released until they didn't.
