Back in 1988, we examined the physiological and perceptual responses to riding w/ and w/o toe-clips in n=14 cyclists:

As you would predict (given that most people don't actively pull up on the pedals, at least during steady-state cycling), there was no discernable difference between the two conditions (in terms of heart rate, perceived exertion, blood lactate levels, or O2 cost).
27 y later, the good folks at Global Cycling Network have repeated the same experiment (for n=1) and shared the results via this entertaining video:

In keeping with our results, their findings were also that it is pretty much a wash. However, the point of this post isn't that the experiment has been done before, but to contrast the two ways of conveying such information to the cycling public. To wit, I expect that their effort will have far bigger impact on end-users than our results ever have, because they have leveraged the "direct-to-consumer marketing" power of the internet to share their data with those for whom it has the greatest relevance. So, kudos to them!
