I'm 6'5" with a 37" inseam and size 15 feet...I get the not fitting aspect of airplanes. That said, I've got over 600 hours in a Cessna 140, including eight hours with a 270 pound instructor.
I find I can fly just about any airplane if I take my shoes off, and no airplane if I don't. I eventually got a pair of boar-skin moccasins made so I'm not barefoot over the Sierra's, but that's all the shoe I'll fly with. If it's really cold I wear down booties or waterproof overshoe and heavy socks.
I'm 6'4" 240 and I fly without shoes as well. Better finess, and makes us shorter! Something to keep in mind OP, could help!
Also moved my seat back some from what it was originally designed to do.. but that is getting off topic and a whole other discussion.
