That is exactly what I saw, thanks.
Even though I didn't catch the name of the bindings, the guy using them said that he really liked them. He was somebody who was into trees and powder; he also carried collapsible poles... so not a snowboard park type.
I use Flows and I really liked step-ins a decade+ ago so these sound like a great concept.
