Good call on the jacket - I can see that too.I think LE might have an idea because they have seen the video that the still came from and watching this person walking might clue in more on the feminine/masculine walk.
The jacket reminds me of one of those shorter crop-like things people are wearing now adays. It seems like a shiny fabric like a puffer jacket, and I tried looking online but don't see anything. Same with the shoes. They look like clogs to me, but shiny in some photos and not shiny in others. So frustrating to have so much information, yet so little at the same time. lol
The shoes remind me of these (just shiny/glossy crocs), at least as much as I can tell with the quality of the photo:
Crocs are, at least in my experience, difficult to run in though. So if the person in the photo was also the person running after the POI in the video, it might not be crocs.
