I really like Punf's Trained Panicking and Xayrn's Reinforced Doris has a lot of potential, either as a dwarf skill (Doorf) or with maybe Spin Around instead of one of the Immovables, since doris are for spinning in and that's also kind of what doors do. Not sure why that wasn't the submission, but also not sure whether Spin Around is enough of a move card that it would qualify as a boot. It would be a pretty good boot. I voted for Vholes' Ziggurat Spike. I think the monster card has a lot of utility and using the top of a ziggurat as a shield just seems like a flawless idea.
