Or maybe just famous barefoot characters? Of course there is the famous scene in Chariots of Fire where the whole running team is running barefoot on the beach. The first Die Hard movie has the main character barefoot the whole movie. One of the Predator movies, Predators, with Adrien Brody, features a Yakuza character who, when he realizes he's being hunted, grabs a ninja sword and ditches his shoes. Love that scene. I actually can't think of any more. I'm discounting all the Tarantino and Rodriguez foot fetish scenes. There must be more? Oh, I think The Beach the characters were all barefoot most of the movie?
in My Neighbour Totoror, my favorite japanime, Satsuki running quite a lot because she's looking for her sister. Exhausted, she cant run anymore, take her shoes off and keep on running : https://accroupietpiedsnus.fr/2013/12/21/dustyfoot-satsuki/
Also, as mentioned in the fiction thread, Avatar. Sequel one coming out soon. And, I forgot that the Mel Gibson-directed movie Apocalypto has barefoot indigenous folks, and at least one running scene.
