Trying to move from double hard boots (Fogmans) to reflex-like front boot, worried what to try as a back boot. Rear toe does not work, short booth that don't hold the heel do not work as well. Most people say Wiley's rear boot but I never liked that very much. Release of the back foot is a concern, of course, as is the "feel" of two boots, without which it may take too long to get used to the new setup. Ideas, anyone?
