Several weeks ago, took a walk in the park after a heavy rain and muddied the shoes really bad. So... barefoot. Normally I stab the clutch with quite a bit of force. Not only did I have to use much less force but also had to be more precise in my aim. I don't think it'd be much fun having the foot slip off the clutch pedal.
Recommend keeping foot *completely* off the clutch pedal between shifts. A lot of people inadvertently ride the clutch that way.
Just lazily holding my fingers over the keyboard, there have been times when a... dddddddddddddddddddddddddddddddddddddd or other letter shows up on my screen. (particularly when sleepy)
I have size 12 as well and drive in dress shoes, boots, and sneakers w/o issue. When clutching out in first gear I keep my heel grounded until I'm going quick enough (like 5 mph) to completely release the clutch. After that I ground my heel and rest the ball of my boot on the clutch until i'm ready to shift.
