Okay, so I tried it again (and tried getting squished around the place I remember the foot to get stuck). It happened again when you start going over those cans, The first two cans, one is horizontal, while the other diagonal with something on it (that makes you unable to jump and you slowly go down). I got squished while stuck on that diagonal can, and the foot got stuck.
Hope it helps! :)
If you're still not sure where that is, I can go again and take a screenshot of the place.
