I haven't seen the movie in ages, so I'm not sure if it's the same, but when I was in USN regs mandated "Flight deck" boots. They had to be all leather, with no nylon or gore-tex or anything of the sort. My pair (which I can't find now) had an additional piece of leather across the toe.
Also, I can't find my flight suit, but from the pics it looks to be pretty standard. From what I remember, though, is that over the years pockets/pouches were added or moved just slightly. The older style, if I remember correctly, had an added pouch on the thigh. From what I can tell, it looks like he has that pouch in this pic.
I know that my flight suit doesn't have it. Mine is a newer style, though. I think I got it around 2000 or so. Mine was used as flight suits were a pain to get as they were replaceable items for the flight crew. I was authorized to wear one on missions if I could source one, but because I wasn't normal flight crew it was a pain in the ass.
Good luck.
EDIT: The patch is most likely the carrier air wing patch or something similar. The patch on the left (his right) breast should be a unit patch, which leads me to believe the triangle patch is for the larger overseeing body he's a part of. Basically the breast patch would be his specific squadron or detachment while the triangle would be the air wing that oversees all the squadrons on the boat. I hope that makes sense.
