Well now, I wouldn't say my feet are akin to those of a giant frog, but they are the opposite of skinny and delicate; I'd say they are more like a bear paw (sounds more masculine) 
Really good stuff covered here, from enlarging that foot-well area by skinnying up that side panel to tunnel clearance as much as possible (I've done some of that, and I am running the stock 74 thin side panel), shimming out the pedal box with spacers (going to try that), rounding off the bottom right corner of the brake pedal (just did that, looks like a racer boy mod from back in the day), and yes, definitely have to choose my footwear wisely - but my feet are on the wide side, there is a limit to what I can accomplish there (bear paw).
