I find it hard to believe that boots can be cranked hard enough for this to happen, that and the board should be up on edge long before this is even a possibility. Been riding Heads for 6 years with blue BTS, great boots.
This is what Dremels are for- just make a cut to head off the cracks. BTS stands for (B)etter (T)han (S)lamming (your face on the ground) which is how I felt before I installed them.:) Keep on keeping on.
Have you checked your right hand? That's the last place I remember seeing it. I know the feeling- each time I leave the house I have to look down to make sure I have pants on.:D
