Right. I think 3x3 with Feet lies in an otherwise untapped space between regular (or even one-handed) 3x3 solving and 3x3 FMC. You have to keep your solutions efficient due to the lower TPS, but not so efficient that you waste time. The event is not inherently unsanitary—especially when compared to unwashed hands—and anyone with rather gross feet can just wash them before solving. And if an organizer doesn't want to deal with it? Well, nobody's making them include the event anyway.bring it back because the reasons to remove it weren't good. also in general feet heavily prioritizes move efficiency and ergonomics so maybe move efficient Petrus could be viable.
Foot can be smelly if you sweat a lot but I think that is solved by washing and showering
Some people such as Feliks claim that the event brings down the reputation of the WCA due to its perceived gross nature, but I don't think that's actually the case. Whenever I tell somebody that some people can solve cubes with their feet, the reaction isn't usually "Yuck, that's gross"—rather, it's "Woah, how do they do that?!".
In any case, I'm getting a bit off-topic from the original thread. Feet should come back in my opinion, alongside Kilominx, FTO, Master Pyraminx, and 2x2 MBLD.
(There's also the question of whether the WCA should be considering new events in the first place. I'd argue that more events are always better, providing that the events actually add something new and unique to the table, but that's a discussion for another time.)
