I just saw some Look pedals that have an adjustable q-factor. What advantage is to be gained by increasing it from 50mm to 60mm? Thanks

Personal preferences/your physiognomy dictate what works here; like much of cycling "fit," it's best derived empirically. Supposedly, those of us with larger hips, and thus leg "set," would benefit from a larger Q-factor, as it would place less stress, laterally, on the knees. Many riders, though, especially smaller ones, wish to keep the Q-factor to a minimum, as is currently fashionable. It's a lot like saddle tilt, though; what's comfortable for you is probably what's right for you. Given that most of us didn't even know what the Q-factor was until fairly recently, and managed to ride millions of blissfully unaware miles, I suggest you not obsess about it, unless you're getting knee pain.

Take a look at how far apart your footprints are. If that's your natural "Q" dimension, you'll never match that with any bicycle crank/pedal combination.

The only reason I can think of for wanting more widely spread pedals would be if your heels were hitting the chain stays.
