I'm 5'8.5" with a 32" inseam, and have no trouble flat footing when wearing boots. Even in sneakers, I'm almost flat footed. Really, getting both feet flat is not necessary. If you have the balls of both feet on the ground, or one foot flat and the other on your toes, you're really okay. It's not like this bike weighs 600 lbs. Hardly anyone can touch both feet to the ground on a dirt bike, but once you learn to ride one it isn't a problem. You wouldn't want a street bike THAT tall, of course, but leaning over a bit while stopped is no big deal, and not really even a small deal.
