Stoked is a cartoon series by the creators of 6teen and Total Drama. Being a surfing series, it often features many of the characters barefoot while swimming or walking on the beach or riding a wave.
The animation style tends to give the characters comparatively small feet, so they are usually not very detailed unless zoomed in on during specific scenes.
Here are some characters who have been barefoot in the show:
