I'm wondering if there's been any discussion of the merits of forgoing being lashed into your road bike. This video from GCN news convinces me that unless you're doing all out sprints there's little to be gained and possibly even something to be lost by using anything other than the old-fashioned flat platform pedal.

I would think having the ability for ones foot to float on the pedal to its most natural angle throughout the stroke might offer benefits of less repetitive motion injury and, as the video shows, there seems to be no loss in efficiency.
