I have been using Reflex front bindings for a couple years. Started using the thick padded liner at first with the black shell. After a few months I decided to try an intuition liner. I molded it a few times trying to make it fit better without pain. I did get it molded comfortably and securely but could never get a very good stack because it virtually removed all ankle flex. I switched back to the thick liner and finished off the season skiing much better and more consistently. Last year I swapped to the white cuff Reflex shell and stayed with thick liner.
I've been doing a lot of snow skiing with intuition liners this year and have learned that the way the liner is molded makes a huge difference. For those who have success with intuition liners in waterski boots, how did you mold the liner?
