Reading this I realized that when doing my throw, I haven't really been engaging my toes and feet at all. I went back and watched the crush the can videos and during a demonstration of coming over the top/not bracing against the right side, Sidewinder mentions "throwing flat footed".
Now this stuck out because I have fairly flat feet, and have actually worried from time to time that this would prevent me from being able to shift properly. So I then tried to just bounce on the balls of my feet/ toes, back and forth
Just a bit of disambiguation, and I think you have it conceptually, there's a difference between being "flat-footed" and having flat feet. The first is mostly about weight being distributed evenly front and back over your whole foot (not being in an athletic position). The latter relates to the arch of your foot, which will have some bearing on athletic motions.
I'm not familiar with the details of the impact of having flat feet, but having played other sports with some people with flat feet, they have mentioned some issues with balance because of it. This is probably something you're aware of.
