I didn't really "Have to ask" but I wanted to see if anyone knew if it was possible or not. Then I decided to take the toes off and see how the reflex part worked. It looked like switching toes woudln't affect the release or retention so I switched the toes two days ago and indeed, release and retention were not changed. The only difference is the "Reflex" mechanism isn't attached. I have skied them the last two days and they seem the same and I don't even notice that the reflex is detached.
