John not sure you knew this or not as I did 'not' I just found it in there video.
After you tighten the ratchet's if you push the release lever 'down' it will actually lock the ratchet so it won't open or close. That is a very similar feature to the 2010 SE's mini ratchets that you could lock.
the set-up video also mentions as Random pointed out flipping the toe caps around binding to binding. If I have to I'll try this but we will see how they work with my boots tomorrow.
