No backs are far from a new or original idea. There were quite a few people rocking no backs in the early to mid ninetees. At one point the big thing was baseless with no or low backs and cut-down boots. The boot tech wasn't up to par yet so blown up ankles were also popular.
With modern boot designs, that actually offer support and function, no back riding is coming back around. I like running no backs in deep pow, freedom! You don't need special bindings to get this feeling though (unless you ride some backdoor binding design.) I just use Flux without the highbacks on, I adjust the straps to fit and move the binder one set of holes toward the toes to make up for the offset. If you like it then buy some mid-range binders and make your own permanent pair. You don't need a high end stiff baseplate for this, the idea is a looser and softer feel.
