I've seen this video on a program called "None of the above"
This isn't fake, in saudi they have alot of sand on the highways.
With their sandals standing on the road, ( wich has sond on it ) their surface is getting decreased to about the site of a knot.
They technically standing on mini plates with a tiny surface. If you multiply those little plates ( sand ball ) with alot under your feet, your surface is decreased.
Since you're standing on all the million sand balls that are on the highway.
It's not fake, it's real and i've seen it.
