The Ride Insano fits exactly what you are looking for except for maybe the footprint.
It's super stiff, double boa, very light and the boot overall is pretty low profile but I don't know if the footprint is supposed to be smaller. The footprint is the same as my old size 12 Vans Fargos that I have used with a TRice 161.5 no problem. I think the TRice has a 260 waist if that helps give you an idea.
I liked the DC Judge when I tried them on but they weren't as stiff as I was looking for. Super comfy though.
Salomon F22 is pretty stiff and extremely low profile (liner fused with the shell). I wear a half size larger in these than standard salomon boots...so lo-pro, in fact, that, wearing their 10.5 F22, I'm able to comfortably bump down to a medium binding.
No boa, but as others said, Salomons proprietary lacing system (Powerlace Pro) is very good and relatively fast.
