I'm only 6', but have the same issue with my work boots getting caught on either the pedals or the dash parts. Worse in the winter with the Rocky boots, of course.
Has anyone spaced the gas pedal mount further towards the driver to equalize the pedal height some? Seems like many of the newer vehicles the gas pedal is much further into the firewall than it should be - results in sitting crooked in the seat to drive it. I drive with both feet - one on the gas, one on the brake and that height difference drives me nuts. I wish they would also stop putting such a high offset in the brake pedal off to the right side - makes it tough to use your left foot for braking.
