If you put a fabric covering on any flexible structure and then flex it, the fabric has a tendency to gather at the joints. I'm surprised he has not elastic straps on his ankles as well as I'b bet without the usual forces in play I would think his pants would ride up his calves towards his knees as well.

There is an entire community of people however who collect "evidence" that the ISS is a hoax! This would be exactly the kind of "proof" they'd love!
