My pedals are 14" long to provide ample space for my bare foot with all of it's contact points: toes, metatarsophalangeal joints, arch, and my calcaneus. And I affixed cushy pedal covers for comfort.

My Z10 actually takes the place of shoes and since my feet are actually in contact with my wheel at all times I am more sensitive to any out of the ordinary performance issues that may arise. Here's a picture of version 3 of my suspension pedals:
