What's the evolutionary advantage to having large feet?
I can't really think of what benefit it could possibly give other than maybe faster swimming or kicking things, but for that most kicks in martial arts are done with the shin rather than the foot.
also, people with bigger feet have bigger calves, as it gives you that extra bit of push on your gait.
also, for boxers, it makes you punch marginally harder, given the extra bit of push you get from your calves. (believe it or not, any punch in boxing uses the whole body, thats why they hurt so much)
tl;dr bigger feet = bigger calves = more power
also better balance etc.
I only mentioned that because since I figured that just meant shins were more optimal for kicking. You're probably right about it being a stupid thing to bring up though, my mind has just been all over the place lately
