thanks again to the live chat tech who suggested these bindings for an old (42) man who wanted easy on/off for his new board.
these things rock! here's the skinny:
to maximize the rear entry deal, you have to be able to set the back foot binding loose enough to slide your boot in or out of it while on the go. so this means a much looser setting than one would ordinarily have. depending on the kind of riding you do, this may not give you enough control, but for me - a free ridin', no tricks type - it works surprisingly well. the adjustable heel gives fabulous support and one can compensate for the looser fit over the front of the boot with a bit more angle forward on the adjustable heel. is that confusing? sorry.
you can get the back foot into the binding on the lift so you can just ride off on top! how awesome is that?
to do it, slide to the far side of the chairlift (I ride goofy, so it is the left side of the bench), reach down and grab the heel of the binding, slide your boot in, and slap the thing shut. totally easy. just don't fall off...
