I’ve never seen a velcro wrist strap cause a person’s thumb to so extend and bend in such an unusual disjointed manner - do you have an example? In other places in that particular video that same glove is clearly within a black square edited into the picture. All of these Floyd videos have clearly been wholly produced + edited so it’s hard to distinguish anything real within them.
It’s not his thumb, it’s the wrist strap sticking up; ie: not closed. It’s by his wrist bone, where the strap/closure should be, no one grows thumbs there.
Steven, if you look at his other hand you can see the strap on that glove sticking out.
It’s a velcro strap, he has one on the other hand as well. I have the same issue if I fail to fasten my sailing gloves.
