I'm 6'6" and, sad to say, 280#. Size 15 shoe.
I'm a first time builder and chose FFR for a lot of reasons I won't get into here. But one of them is customization. You didn't say if building was an option but by doing some basic mods to a standard build I've gained ~4" of legroom. The first is a simple way to gain ~2" and, I would assume, could be done on any car. I have a Kirkey lowback seat mounted to the floor all the way back. The seat is made out of aluminum and is therefor very thin. For the add'l ~2" I bolted in a vendors adjustable Wilwood pedals and adjusted them all the way forward. Other comfort mods: I trimmed the brake pedal, got aftermarket driver's footbox aluminum and bent my throttle. I'm go-carting it now in tennis shoes, which is better than I had hoped for at the beginning of the build. I have some Simpson driving shoes and there is plenty of room with those on. I'm doing some add'l clutch foot mods as well; re-doing the footbox crash bar, which really doesn't work for us Sasquatch. Lastly, I'm also adding a dead-pedal.
BTW if you plan to buy something turn-key instead of building, you could always have a pro build it for you with those mods.
HTH,
