I'm one of the ones in favor of an option for a practical shoe. Doesn't need to displace the current one or anything, but I like the option to customize to something easier to fight in. I've practiced martial arts in high heels before (training and teaching for self defense applications) and while there are ways to use that shoe in a fight to one's advantage (it makes a mean foot stomp), it seems a bit silly to think that a career warrior who has to fight on lots of terrains would never feel the need to kick off the heels.
