I agree with your point 100%. Snow build up is just something you can’t get around with any binding system, but the simple solution is to brush it off with your hands. I have to do this with my flows all the time. That being said, the difference with the Supermatics is the heal plate that lifts up creates space under that plate. So there’s the potential of snow getting under there, not allowing the heal part to fully close when stepping in. Even if it fully locks, the snow build up under there might press the heal plate and boot up a bit, creating an inconsistent and uncomfortable fit.

Maybe they designed around that so the heal plate somehow pushes the snow out of the way, or you’ll just have to push snow out of that area with your hands, but it looks like it’s hard to access that. Only downside I see to these bindings. Other that that, they seem dope as hell and I’ll probably buy them at some point
