I've just seen a fourth apparently sane, apparently adult human being walking around town wearing a pair of running shoes with toes. I really do not consider this acceptable behavior for a socialized person. Maybe if he grew up raised by wolves with a fixation on physical exercise. Maybe. You want to go running in your super-special toed shoes in order to celebrate the miracle that is hominid evolutionary biology? Go ahead, knock yourself out. But take those damn things off afterward and dress yourself with a little concern for not looking like an idiot. We evolved culture and subjective social standards only a short spell after we evolved the spiffy sprinting feet. Catch the fuck up.
