Her cast system (1st edition not the new ones) seems to be having some issues.
"One of the toe pieces is having a lot of trouble aligning and locking into place, to the point where it's taking over ten minutes to get it locked in and I still popped out mid-tour. The pins are completely aligned but the binding just won't get close enough together to lock it in. This happens with both boots and does not happen with the other toe piece.
Second, the higher risers seem to not lock in place. They keep clicking against the boot heel piece and going down an inch or so with each step, not staying straight up but shifting to be diagonal. This obviously causes a lot of problems with touring uphill, leading me to have to use the lower risers instead which is not adequate for some of the steeper hills.
I'm hoping there is an easy fix and this is all user error, but I've tried looking up this issue and watching some videos and I'm still at a loss. I reached out to Cast this week but have yet to hear back. Thanks for any help anyone can provide!"
